Location: Placer claims on Sanona Creek, a tributary of Tyone Creek, extend for about 3 miles downstream from the mouth of Fourth of July Creek. The center of these claims is at an elevation of about 3,000 feet on Sanona Creek. The location is accurate to within 1/2 mile.
Geology: The rocks along Sanona Creek in this vicinity consists of volcanic rocks, sandstone, and argillite of the Talkeetna Formation (Csejtey and others, 1978). Gold occurs in alluvial gravel deposits estimated to be more than 50 feet thick (Kurtak and others, 1992). The valley bottom is 400 to 800 feet wide, and the average stream gradient is less than 40 feet per mile. Thirty-three mining claims were staked in 1980 and one claim was staked in 1983 (Kurtak and others, 1992). One placer sample collected by the U.S. Bureau of Mines contains a trace of gold (Kurtak and others, 1992).

Age: Quaternary placer.
Reserves: An estimated 30 million cubic yards of potentially auriferous, gravel are in the upper part of the drainage; no grade estimate has been made (Kurtak and others, 1992).
