|Location and accuracy||Kal Creek, about 6 miles northwest of Boundary, is a small north tributary of Squaw Gulch. Kal Creek was referred to as Kalamazoo Creek in the early 1900's. The location of placer gold mining on Kal Creek is uncertain; the coordinates are near the mouth of Kal Creek, in section 3, T. 27 N., R. 21 E., of the Copper River Meridian; the location is accurate within 1 mile.|
The rocks in the vicinity of Kal Creek are Paleozoic amphibolite-facies metamorphic rocks that have been intruded by plutons and dikes of probable Jurassic age (Foster, 1976; Szumigala and others, 2002).Ellsworth and Davenport (1913) reported placer gold mining at the head of Squaw Gulch, near the mouth of Kal (Kalamazoo) Creek. A small open-cut mining operation was active on Kal Creek in 1999 and 2000 (Norm LaFramboise, Boundary Explorations, Inc., written communication, 2000). Prindle (1909) reported that gold was found in a conspicuous outcrop of vein quartz and quartzitic schists about 1,000 feet long and 50 to 100 feet or more in width on the ridge south of Kalamazoo Creek (see EA149); local miners believed this to be the source of gold in the creek. There has been placer gold production on Squaw Gulch (EA147) downstream of Kal Creek.
