5 18 24 July 1979 harris well. All looked (the adults) (we saw them from about 1/4 mile away). could it be that a tough jackass got involved with a band of horses and became father to the mules? That's what it looks like. Description of Plinney Spring: up canyon from mine shafts and structures, following pipeline. A small seep from camper wall runs downstream maybe 100-150 feet, owhere more than 1 foot across and one inch deep. Dense growth of grasses (Elymus) and sedges. Pipes piled up and several rusting pieces of metal, a mine claim marker at the head of the spring. Surrounded by pincus. Bird list, next page. No rabbits seen on peak, but rabbit sign (cottontail and jackrabbit) found. saw a young jackrabbit on ridge just N of camp (mine shaft). No bats seen this trip!
