Agency: NF Region District: R1 Ranger District: STEVENSVILLE Forest Service Tract: Watershed Code: 17010205 Forest or Resource Area: BITTERROOT Owner: N Impact: U Report: Cleveland Mountain mines (RA002354, RA002991, RA002981) These mines were grouped because they are all in the same vicinity and there are no definite boundaries for each site. They are east of the Threemile Wildlife Management area and west of the Granite and Ravalli County divide. Forest Route 1310 was closed off and so the last mile and a half had to be hiked. The area was visited while there was still some snow on the ground (5/24/01). One 10 ft, highwall was found at the Cleveland Mine but all the adits had caved. The larger of the three caved adits was possibly 100 ft in original length and another was greater than 50-60 ft originally. Trenches and pits were scattered through the forest adjacent to the main workings. All the adits trended N.45 to 55 E. Large chunks of quartz vein were on the waste-rock dumps and <5 percent sulfides and oxides were in the vein material. Sahinen (1957) described the geology as "blocky, banded blue-grey argillite with some quartz containing specks of limonite, specular hematite, and magnetite". Close (1982) described the Cleveland as "one trench and three caved adits" that extended along a "northeast-trending fracture zone with quartz veins and pods in quartzite and argillite". Along the ridge, numerous small pits had been dug for exploration (these may have been the "Ellen M. Claims" and the Cleveland Summit prospect). Over 26 separate pits and trenches were counted along about a ½-mile of the Cooney Summit / Cleveland Summit trail to the top of the Welcome Creek Trail. No environmental concerns were noted. The typical prospect was about 10 ft by 5 ft by 3 ft. Also the Cleveland Spring prospect was not located with certainty, but it was described as "two pits and one trench" (Close, 1982). |
