This THP lies between Arnold, CA and Dorrington, CA near Highway 4 and Calaveras Big Trees State Park (sections 14, 15, 16 and 21 are adjacent).  Sierra Pacific Industries is planning a mostly clearcut tractor and cable logging operation in ponderosa pine, sugar pine, white fir, Douglas fir and incense cedar forests at an elevation of 3,900 to 4,880 feet.  There are 3 unstable areas including steep swales in units 1203 and 1937, a fill slope failure on full bench excavation, and hummocky terrain in units 1253 and 2156.  SPI wants to use excavators on slopes up to 30% grade that do not flatten before reaching a watercourse, and on slopes less than 50% grade for site prep and fuels treatment.  7 road drainage sites are planned for work including rocking, dip construction and culvert repair and replacement. More information is available on the THP Tracking Center website.
