Hinsdale County
Burrows Park District (aka Whitecross District; aka Park District)
This district is possibly an amalgamation of several districts, but at least has several names. Henderson provides very a very specific location for the Park District, listing 16 sections in three different townships that appear to be the same as other descriptions of the Whitecross/Burrows Park District. Dunn (2003) indicates that the Burrows Park District may have originally been known as the Park District, which seems to fit with Henderson’s description. She notes that Hinsdale County was divided into six districts by the state legislature in 1893, of which the Park District was one, along with the Carson, Cimarron, Galena, Lake, and Sherman Districts. Mindat.org (Sep 2015) considers the Burrows Park, the Park and the Whitecross to be the same district, a convention we follow here.
Vanderwilt (1947) considered the Burrows Park District, which he described as sitting at the head of the Lake Fork of the Gunnison River, to be a continuation of the mineralization of the Silverton area. Wilson and Spanski (2004) aggregated the Burrows Park District in with eight other districts as the “San Juan Mineralized Area.” The connection is that they appear to lie within the San Juan caldera of Steven and Lipman (1976). (The other districts in this grouping are the Galena/Henson Creek, the Sneffels, South Ouray, Eureka, Telluride, Ophir, Red Mountain and Lower San Miguel, of which the Galena is in Hinsdale County.)
The geology consists of tuffs and flows associated with the Oligocene San Juan caldera complex, with an outlier of Precambrian granites in the middle (Vanderwilt, 1947). Mineralization consists of “filled fissures grading into replacement types” of chalcopyrite ore, sphalerite-galena ore or gold-silver ore with small amounts of lead and zinc (Vanderwilt, Ibid).
Eberhart (1969) discusses the three settlements that arose around Cinnamon Pass – Whitecross, Tellurium and Sterling. He indicates that the harsh winters and associated transportation problems inhibited both the mines and the towns.
