|Location and accuracy||Balm of Gilead Gulch is a small south tributary of Crooked Creek. Crooked Creek is a short, 2.3 mile long west tributary to Ophir Creek. The mouth of Crooked Creek is 7,500 feet upstream (on Ophir Creek) from the southern boundary of theBendeleben quadrangle. The mouth of Balm of Gilead Gulch is 4,500 feet upstream of the mouth of Crooked Creek. This is locality 82 of Cobb (1972; MF 417; 1975; OFR 75-429).|
Geologic descriptionDetrital gold was recovered from fractures and crevices in limestone (marble) bedrock. The gold-bearing bedrock was covered by 5 feet of soil (Collier and others, 1908). Bedrock in the area is metasedimentary schist and marble of a Lower Paleozoic assemblage (Till and others, 1986).
