|Location and accuracy||The Burke and Lange prospect is about 0.4 mile north of Hollis and about 0.5 mile north-northeast of the center of section 4, T. 74 S., R. 84 E. However, there is no report of anyone seeing it since Chapin (1918), and the location may not be accurate.|
Geologic descriptionAt this prospect, Chapin (1918) reports a quartz vein about 20 feet wide that strikes N70W, parallel to the layering in greenstone tuff of Silurian or Ordovician age (Herreid and Rose, 1966). The only work was surface stripping.
