This THP is about 6 miles east of Highway 4 and Dorrington, CA and about 3 miles NE of Calaveras Big Trees State Park at an elevation of 5,600 to 6,400 feet.  Sierra Pacific Industries is planning a mostly clearcut tractor based logging operation in Ponderosa pine, sugar pine, white fir, red fir, Douglas fir and incense cedar forests.  The THP area drains into the North Fork of the Stanislaus River.  SPI wants to use ground based equipment on existing roads for skidding operations inside class II (mid sized) watercourses within units 4784 and FB1, and use class III (intermittent) watercourse crossings during the winter period.  35 road drainage sites are planned for work including rocking, dip construction, culvert repair/replacement and re-construction of washed out crossings.  There was a 2009 goshawk nest reported in section 33, and Sierra Nevada yellow legged frogs were reported at crossings for haul roads 5N02 and 5N13, and at a waterhole near road 5N13.  CA spotted owl territories were reported in sections 9, 11, 13, 17, 21 and 33.
