OPINION BY
President Judge PELLEGRINI.1Dutch Corner Historical Society (Society), Estate of Joseph W. Imler, Jr. (Estate), and Neal and Linda Buterbaugh (Buterbaughs), (collectively, Petitioners), appeal from the Pennsylvania Board of Property’s (Board) order dismissing them caveats2 to the two patent applications filed by Allen K. Stahl under the statute commonly known as the Public Lands Act (Act), 68 Pa.C.S. §§ 6101-6114.3 We reverse.
By the Royal Charter of March 4, 1681, King Charles II of England granted “William Penn, his heirs and assigns ... make, create and constitute the true and absolute proprietaries of the Contrey [Pennsylvania]” conveying to him “an immediate and absolute estate in fee to the province of Pennsylvania.” Thompson v. Johnston, 6 Binn. 68, 70 (Pa.1813) Throughout the proprietorship, lands were conveyed by warrant4 and patent by the Land Office which has operated continuously since William Penn arrived in Pennsylvania in 1682 and began to administer and sell land.5 In 1779, the Commonwealth bought out the proprietorship and assumed title to all public land not yet conveyed.6 The Land Office has been housed in various departments of the Commonwealth over its history. In 1981, the land records and the functions of the office, which had been in the Department of Community Affairs, were transferred to the Pennsylvania Historical and Museum *1203Commission (Commission).7 Among other duties, the Commission has the duty to maintain and preserve papers relating to the surveys of this Commonwealth, reports of commissioners relating to the boundary lines of this Commonwealth, and maps and other papers lodged with the Land Office. 68 Pa.C.S. § 6102. Commonwealth land records only document transactions between the Penns or the post-revolutionary Commonwealth and the first purchaser(s) of each tract of land.
A person may apply for a warrant to have a survey made of any tract of vacant or unappropriated land. 68 Pa.C.S. § 6103. Land is “unappropriated” when no patent has been issued by the Commonwealth. 68 Pa.C.S. § 6101. Land is “vacant” to which no office rights are outstanding. Id. The Department of Conservation and Natural Resources (DCNR), with the cooperation of the Commission, is to determine whether office rights have been granted for a tract of land and whether the tract of land is vacant or unappropriated once an applicant makes a proper application. 68 Pa.C.S. § 6103(c). The applicant is required to give 30 days’ notice of the application in a “publication once a week for three successive weeks in a newspaper of general circulation in the area where the land is situate.... ” 68 Pa.C.S. § 6103(c)(2).
On April 2, 2008, Stahl filed two patent applications with the DCNR for vacant and unimproved land at the summit of Evitts Mountain in Bedford County. The first application involved 57.44 acres of land in South Woodbury Township on the east side of Evitts Mountain based on the Kochendarfer and Brumbaugh Warrant of 1851. The second application was for 75.18 acres of adjoining land in Bedford and South Woodbury Townships on the east and west sides of Evitts Mountain.
On December 18, 2009, Buterbaughs, who own land on the southwestern side of Evitts Mountain from the Ross Warrant of 1794, filed a pro se caveat asserting that Stahl did not follow warrant and patent procedures under the Act, and that Stahl had rebuffed their attempts to resolve the dispute. On March 23, 2010, the Buter-baughs and the Society filed an amendment to the caveat asserting the Society’s interest as the grantee of an easement from the Buterbaughs, and that the Buter-baughs owned and improved8 just over *1204two acres of the lands claimed in the applications. On April 16, 2010, the Estate and the Society filed a caveat contesting the claim that the other parcel was vacant and unappropriated by chain of title and survey. They also alleged that the Estate’s property, from the McCurdy and Cisna Warrants of 1794, adjoins the Buter-baughs’ property from the northeast side and across the summit of Evitts Mountain. The Estate’s land is bounded on the boundary of the Cisna, McCurdy and Adair Warrants.
On September 1, 2010, a DCNR Professional Land Surveyor (PLS) James J. McElwee (PLS McElwee) filed a report with the Board on the applications and caveats, concluding that the vacant lands existed as asserted and that patents should be issued to Stahl.9 On October 22, 2011, the Board notified Petitioners of PLS McElwee’s report and Petitioners requested a hearing.
At the hearing, Mr. Buterbaugh testified that he bought a 50 to 56-acre parcel on the western side of Evitts Mountain in 1994 and informally surveyed the property himself. Mr. Buterbaugh said that Ken Schulze (PLS Schulze) surveyed the property for him in 2007 and 2008, and located 2.03 acres of vacant land, and that he put up barricades, a tree stand and “no trespassing” signs on that land. He testified that his family have hunted and ridden horses on the 2.03 acres since he purchased the property in 1994.
The Estate’s administrator, Joseph Im-ler, testified that his parents lived on the property for 64 years and told him that their property went over Evitts Mountain, onto the other side, and bordered the Bu-terbaughs’ property. He stated that the Imler family used the land on the summit for hunting, horseback riding and hiking, but did not erect any fencing or other markings to define the property boundaries.
Laura Jackson, who works with the Society, testified that Dutch Corner is a designated rural historic district with many trails on either side of Evitts Mountain, many of which were preserved. She stated that Stahl’s proposed use of the land as a wind energy project would make the area unavailable for public use.
PLS McElwee testified that a connected warrant map had to be constructed because one was not available for this area, and that he reached his conclusions that vacant land existed based on this map. He said that none of the connected warrants for the Estate’s or Buterbaughs’ property reference the top or summit of Evitts Mountain so neither the Estate property nor the Ross Warrant, from which Buterbaughs’ land proceeds, go to the top of Evitts Mountain. With respect to the Buterbaughs’ property, he stated that while a filler warrant was put in between the Kochendarfer and Brumbaugh Warrants and the King Warrant of 1794, the source of Stahl’s adjoining parcel, the Ross Warrant and not the Kochendarfer and Brumbaugh Warrants, was the source of the Buterbaughs’ title and the Ross Warrant does not go to the top of Evitts Mountain. He stated that he disagreed with Norman Van Why’s (PLS Van Why) *1205reliance on John Fluck’s (Fluck) 1886 resurvey of John Bennett’s official 1881 boundary that extends the Ross Warrant line by 27 rods10 to the east.
PLS Schulze testified that Stahl and his father contacted him to resurvey their property and he found vacant property on the top of Evitts Mountain. He said that he created a connected draft of the area, admitted as Exhibit 46 (see Reproduced Record (R.R.) at 444a), while preparing Stahl’s applications for the warrant and patent showing the unclaimed areas alleged in the applications. He stated that he also discredited the evidence and findings of Fluck’s resurvey extending the Ross Warrant line by 27 rods.
Through PLS Van Why, Petitioners introduced a number of exhibits composed of surveys and title documents of other owners in the area. He testified that he believes that the Ross Warrant’s line should extend to adjoin the Garretson Warrant of 1867 to comply with Fluck’s resurvey thereby extending the Ross Warrant line 27 rods to the east. PLS Van Why identified Exhibit 36, (R.R. at 410a), a recorded connected draft prepared by the Department of Community Affairs in 1979 (1979 Connected Draft) of the Garretson Warrant that follows the Fluck drawing and shows the 27-rod extension of the Ross Warrant. He identified Exhibit 38, (R.R. at 412a-414a), a recorded survey map he created in 1986 for another party also based on the Fluck resurvey of the Garret-son Warrant, and Exhibit 41, (id. at 415a), a recorded 1910 deed following the Fluck resurvey. Following the hearings, the Board directed the simultaneous filing of briefs and closed the record on July 29, 2011.
On October 17, 2011, the Board issued an adjudication and order disposing of Petitioners’ caveats. The Board concluded:
[ P] LS Van Why’s testimony does not conclusively establish by a preponderance of the evidence that the vacant land claimed by Stahl in his Applications as found by PLS Schulze and as confirmed by PLS McElwee is in fact already owned. Van Why’s documentary evidence on this issue is bottomed on a draft resurvey made by a John Fluck in 1886 of the official boundary by John Bennett in 1831. According to the evidence, Fluck’s survey was not recorded. There is no evidence of a corrected Warrant having been accepted contemporaneous with Fluck’s survey. Both PLS Schulze and PLS McElwee testified that the existence of the Fluck survey did not affect or otherwise alter their opinion.
(R.R. at 53a). The Board also found PLS McElwee’s testimony persuasive and accorded great weight to his analysis and conclusions. Specifically, the Board credited his testimony that he was required to create a connected warrant map of the area because none existed, (id. at 53a-54a), and his conclusion that “because the lines of the original warrants prevail in a determination of whether vacant lands exist, the [Fluck] resurvey of the Garretson warrant 55 years later could not affect the boundary lines of the 1831 surveys.” (Id. at 54a.)
The Board also rejected Petitioners’ assertions that a patent could not issue under Section 6112 of the Act based on the Buterbaughs’ and the Estate’s improvement of the land. It also rejected that Stahl’s notice of the applications in the Altoona Mirror did not meet the requirements of Section 6103(c)(2) of the Act, 68 Pa.C.S. § 6103(c)(2), requiring “publication *1206once a week for three successive weeks in a newspaper of general circulation in the area where the land is situate.... ” Accordingly, the Board dismissed the caveats and Petitioners appealed to this Court.11
Petitioners first argue12 that the Board erred when it found PLS McElwee and PLS Schulze to be more credible and persuasive than PLS Van Why because that finding was based on improper factors both legal and factual.13 First, they contend that the Board did not give sufficient weight to PLS Van Why’s testimony and documentary evidence and improperly found it was not persuasive because it was based on the unrecorded 1886 draft resurvey of John Fluck. (Id. at 53a.) We agree. The fact that the resurvey was not recorded has no bearing upon its competence as evidence or the competence of PLS Van Why’s testimony or the other recorded documents that relied upon it: the 1979 Connected Draft, (R.R. at 410a); the 1986 map, (id. at 412a); and the 1910 deed, (id. at 415a). See, e.g., Schmitt v. City of Carbondale, 257 Pa. 451, 455, 101 A. 755, 756 (1917) (holding that a map that was found in a corporation’s office, which had conveyed a parcel of land for a public park as shown thereon, was admissible as an ancient document because it was more than 30 years old and appeared to be genuine and had been acted upon by the corporation). Thus, the Board erred as a matter of law in rejecting this evidence on this basis.
More importantly, though, we agree with Petitioners that the Board erred in accepting PLS McElwee’s assertion that there was unclaimed land because *1207no connected draft existed as alleged in Stahl’s applications when there was 1979 Connected Draft prepared by the Department of Community Affairs while it was in charge of the Land Office. Not only does the existence of this connected draft lead the Board in making a determination as to the weight of PLS McElwee’s testimony, it has a conclusive effect.
The former Section 1 of the Act of June 13, 1907 (1907 Act), P.L. 621, as amended, 71 P.S. § 914, repealed by Section 2 of the Act of November 22, 2000, P.L. 652, required the Secretary of Community Affairs “[t]o compile, or cause to be compiled, connected warrantee tract maps of each of the several counties of this Commonwealth, from the records on file in the Department of Community Affairs, showing the outlines of the original surveys, name of warrantees, dates of warrants, dates of surveys, names of patentees, dates of patents, together with such other important details as may appear on the original drafts.... ” The 1979 Connected Draft was prepared by the Department of Community Affairs and certified by its Secretary as required by the 1907 Act.14 It is an official document of the Commonwealth.
The purpose behind the preparation of these documents is public acknowledgement as to what property is to settle and what property is vacant and unappropriated so that title can be settled. Because it was prepared by the Department of Community Affairs pursuant to a direct statutory mandate, this official Commonwealth document, recorded and maintained as part of the Commission’s Land Office records, is conclusive. See, e.g., Smucker v. Pennsylvania Railroad Co., 188 Pa. 40, 43-45, 41 A. 457, 458 (1898) (holding that in an action involving the Commonwealth’s taking of land for a canal, a 60-year old map outlining the boundaries of the taking that was found in the files of the office of public works is conclusive evidence as to the facts set forth therein); Holmes and Holmes v. Public Service Commission, 79 Pa.Super. 374, 380 (1922) (holding that a 70-year old map taken from the Commonwealth records and by whose agents it was made while in the line of public duty for the public taking of property was not only admissible into evidence, but was conclusive as to the matters covered by it.) Because the 1979 Connected Draft is conclusive as to whether there is any vacant land as alleged, the Board erred in giving any weight to the competing connected drafts. To hold otherwise would mean that governmental records meant to settle things would not do so because they could always be collaterally attacked.15
*1208The official connected draft completed by the Commonwealth pursuant to its statutory duty conclusively establishes that the new claim for vacant land as alleged in the applications does not exist. As a result, the Board’s order dismissing Petitioners’ caveats must be reversed because the Board erred in rejecting the documents relying on the Fluck resurvey just because it was not recorded, and in failing to accept as conclusive the 1979 Connected Draft showing that the Ross and Garretson Warrants adjoin and that the land sought in Stahl’s applications is not vacant.16
Accordingly, the Board’s order is reversed.
ORDER
AND NOW, this Uh day of October, 2013, the order of the Pennsylvania Board of Property dated October 17, 2011, at No. BP 2008-0001 is reversed.

. A "rod” is "a linear measure equal to 5.5 yards, 16.5 feet, or 5.03 meters." Webster's New College Dictionary 982 (3rd ed. 2008). In turn, a "perch" is "[o]ne square rod of land.” Id. at 836.
. Our review of the Board's order is limited to determining whether constitutional rights were violated, whether the adjudication is in accordance with the law, and whether necessary findings of fact are supported by substantial evidence. Section 704 of the Administrative Agency Law, 2 Pa.C.S. § 704; Northrup v. Pennsylvania Game Commission, 73 Pa. Cmwlth. 389, 458 A.2d 308, 309 (1983).
. We consolidate and reorder the claims raised in this appeal in the interest of clarity. Stahl argues that Petitioners have waived the foregoing claims by failing to raise them in their Petition for Review. See Pa. R.A.P. 1513(d)(5) ("An appellate jurisdiction petition for review shall contain ... a general statement of the objections to the order or other determination ...”). See generally United Transportation Union v. Pennsylvania Public Utility Commission, 68 A.3d 1026, 1042 (Pa.Cmwlth.2013) ("To properly preserve an issue, a petition for review filed pursuant to Pa. R.A.P. 1513(d), requires a general statement of objections and provides the statement of ' objections 'will be deemed to include every subsidiary question fairly comprised therein.' Issues not raised in the petition for review will not be addressed.”) (citations omitted). In their Petition for Review, Petitioners alleged, inter alia, that "the [Board] improperly weighed evidence and inappropriately disregarded probative testimony and documentary evidence ...” and that "the [Board] made provable factual errors in determining this case ... [and] these factual errors go to the heart of the Board’s reasoning and are errors objectively provable....” (Petition for Review at 2.) Contraiy to Stahl’s assertion, Petitioners’ specific claims in this appeal were not waived because they are clearly subsumed within the general claims raised in the Petition for Review and are fairly comprised therein.
.In general, all determinations of witness credibility and evidentiary weight are solely within the province of the Board and it is not this Court's function to judge the weight and credibility of the evidence presented to the Board. Pennsylvania Game Commission v. K.D. Miller Lumber Company, Inc., 654 A.2d 6, 9-10 (Pa.Cmwlth.1994), appeal denied, 540 Pa. 643, 659 A.2d 561 (1995). However, where, as here, the Board rejects evidence on an invalid basis or fails to appropriately consider a piece of evidence, appellate review is proper. See Leon E. Wintermyer, Inc. v. Workers' Compensation Appeal Board (Marlowe), 571 Pa. 189, 202-03, 812 A.2d 478, 487 (2002); Department of Transportation v. Agricultural Lands Condemnation Approval Board, 5 A.3d 821, 825 n. 3 (Pa.Cmwlth.2010).
. Specifically, the 1979 Connected Draft was certified by the Secretary as follows:
A CONNECTED DRAFT: of forty eight (48) tracts of land, which when surveyed, were situate as follows: forty two (42) in Bedford Township, Bedford County; three (3) in Ju-niata Township, Bedford County; two (2) in South Woodbury Township, Bedford County; and one (1) in Snake Spring Township, Bedford County. The draft has been constructed from and compared with original drafts on file in the Bureau of Land Records, Department of Community Affairs, Commonwealth of Pennsylvania, under the direction of Edward D. Price, Director.
IN TESTIMONY WHEREOF: I have hereunto set my hand and caused the seal of the said Department to be affixed at Harrisburg, Pennsylvania, this thirteenth day of April A.D., one thousand nine hundred and seventy nine.

. While the 1979 Connected Draft is conclusive, it was prepared by the Department pursuant to the statutory duty imposed by the 1907 Act; it is also conclusive because it is an ancient document upon which the public relies. See 24 P.L.E. Evidence § 241 at 280 (2nd ed. 2007) (“Although a map is not ordi*1208narily conclusive as to matters covered by it, [Fuher v. Westmoreland Coal Co., 272 Pa. 14, 116 A. 61 (1922) ], it has been held that a map over sixty years old, taken from the records of the Commonwealth is conclusive evidence as to the facts set forth in it. [Smucker; Holmes.]”). The 1979 Connected Draft states that the Ross Warrant depicted therein, the warrant at issue in this case, was based on the Ross Warrant of April 10, 1794, the Survey of September 2, 1795, the Resurvey of November 6, 1831, and the Patent of April 23, 1870, to Daniel Barley et al. (R.R. at 410a.). Moreover, the cases cited in the Dissenting Opinion, Gratz v. Beates, 45 Pa. 495 (1863) and Sweigart v. Richards, 8 Pa. 436 (1848), are distinguishable because they did not involve a certified connected draft created pursuant to such a statutory duty.
. Based on our disposition of this issue, we will not address Petitioners' remaining claim regarding the adequacy of Stahl’s notice under Section 6103(c)(2) of the Act.
