Necktie Basin: Hanging basin ca 470-830 m W of Warm Springs Mtn summit. These collections from 600-800 m WSW of Summit. Warm Springs Mtn 7.5' USGS Quadrangle; T6N R16W (sections not demarcated). More-or-less flat-bottomed basin of cobbly and gravelly sedimetnary soil. Slopes recovering from burn of 4-5 years earlier; mostly chaparrel elements on slopes. Of note are dead remains of Juniperus californica throughout the lower portions of the basin which have not survived the fire and do not appear to be regenerating. Basin heavily infested with annual, non-native grasses which may have carried the fire and intensified its effects against the original juniper community.
