A chloride spring located in the SE¼, sec. 32, T40N, R4W, about 1.0 km (3,400 feet) SSW of Box Canyon Dam in the Pioneer area and 2.7 km (8,900 feet) WSW of Azalea, S of Lake Siskiyou. NOTE: Coordinates provided are approximate to the center of sec. 32.

Mineralization is a spring saturated with respect to Kenyaite.

The water has a pH of 11·6 and a silica content of 4000 parts per million (p.p.m.), the highest values known to occur in natural ground waters. The rocks exposed nearby consist of two volcanic sequences, one predominantly basaltic in composition, the other highly siliceous. Neither these rocks nor the sedimentary and igneous rocks presumed to underlie the area at depth seem to offer explanation of the unusual mineralization which includes 240 p.p.m. of boron, 1000 p.p.m. of sulphide (as H 2 S), and 148 p.p.m. of ammonia nitrogen (as NH 4 ) in a water that is predominantly sodium chloride and sodium carbonate in character.
