History. Source: R.S. P. 161, § 33. G.L. § 367. G.S. § 442. R.S. 08: § 1130. C.L. § 8614. CSA: C. 44, § 56. CRS 53: § 34-1-53 . C.R.S. 1963: § 34-1-53 .    Editor's note:   Pursuant to §§ 30-6-105 to 30-6-109 , inclusive, there is recorded in the office of the clerk and recorder of Park County in book 70, page 560, and in the office of the clerk and recorder of Jefferson County in book 140, page 400 (indexed in book 2 - Miscellaneous Papers - in the office of the secretary of state), a proclamation showing attachment to Park County and detachment from Jefferson County of territory described as follows:   “Beginning at the intersection of the boundary line between Park and Jefferson Counties with the center line of the South Platte River, about two miles above Lake George, thence down the said Platte River along its center line to intersection of said center line with the Second Correction Line South, thence westerly along said Correction Line to its intersection with the boundary line between Park and Jefferson Counties, thence along said boundary line to point of beginning.”   ANNOTATION   In this section the term “snowy range” is applied to the mosquito spur, but it is designated as “the snowy range east of the Arkansas river”. Bd. of County Comm'rs v. Bd. of County Comm'rs, 9 Colo. 268 , 11 P. 193 (1886).   The mosquito spur of the snowy range, the park range, is a distinct and continuous range or chain of mountains next and immediately east of the Arkansas river, extending from the snowy range at and between the sources of the Arkansas and Platte rivers southward beyond said third correction line; and the summit of this range is the natural boundary between Chaffee and Park counties. Hollenbeck v. Sykes, 17 Colo. 317 , 29 P. 380 (1892).   The continental divide constitutes, in part, the western boundary of the county of Park, at the north, where it is described as “the snowy range, dividing the waters of the Platte from the waters of the Blue”. Bd. of County Comm'rs v. Bd. of County Comm'rs, 9 Colo. 268 , 11 P. 193 (1886).   It was held that in this section the words “up the river”, at the conclusion of the description of Park county's eastern boundary, must be rejected and the call read “thence to the place of beginning”, instead of “thence up the river to the place of beginning”. Link v. Jones, 15 Colo. App. 281, 62 P. 339 (1900).
