Name applied to a 4 mi long boomerang-shaped body exposed along the pedimented southeast margin of the Laramie Mountains in Platte Co., WY in the Northern Rocky Mountain region. Is mapped in southwest part of Johnson Mountain quad (1968 edition; photo revised in 1985) in parts of secs 2, 3, 4, 9, 10, T25N, R70W and in secs 35, 36, T26N, R70W. Named for Boy Scout Camp located in sec 3, T25N, R70W. Type locality is the cliff exposures along the road east of the camp in SW1/4 SW1/4 sec 3. Composed of uniformly massive, speckled pink to gray, medium- to coarse-grained plagioclase-quartz-microcline-hornblende-biotite granodiorite, monzogranite, and tonalite with local poikilitic garnet, minor sphene, euhedral zircon, and apatite and rare magnetite, allonite, and carbonate. Present exposures limited to stream cuts of North Laramie River and its tributaries. Is otherwise covered by Tertiary deposits. Makes non-resistant "grussy" outcrops in small streams, and resistant cliffs along larger streams. Has numerous inclusions of Archean granite gneiss. Rare 1 inch wide aplite dikes cut the granodiorite in northeast part of the body. Cut by a northeast-trending swarm of diabase dikes. Euhedral zircons in the Boy Scout Camp have been dated as 2,051 +/-9 Ma, this date is thought to be the time of intrusion. Assigned to the Early Proterozoic.
