Location: Goodwin Creek, with headwaters one mile east of the uplands of Cape Mountain, flows northward from the continental divide to Lopp Lagoon. Its headwater origin (180 feet elevation) is adjacent to the continental divide and only about 0.5 miles from the headwaters of both Cape Creek and Lagoon Creek which flow southward to the Bering Sea. Wales Creek (not identified on existing maps) may be the first tributary downstream from Goodwin Gulch (TE004). The location of Percy Gulch (Cobb, 1975), apparently another tributary to Goodwin Creek, is not known. Goodwin Creek is included in locality 24 of Cobb and Sainsbury (1972). Cobb (1975) summarized relevant references under the names 'Goodwin Cr.' and 'Percy Gulch'.
Geology: Goodwin Creek passes over Mississippian marble and limestone (Sainsbury, 1972); it does not directly drain uplands of the Late Cretaceous Cape Mountain biotite granite (Hudson and Arth, 1983) or its contact. However, three tributaries, including Goodwin Gulch (TE004), flow northward to Goodwin Creek from headwaters in the uplands of Cape Mountain. Two USBM churn-drill holes (Heide and Sanford, 1948) indicate a narrow pay streak with average grades of 4 pounds tin per cubic yard for 1000 feet downstream from the mouth of Goodwin Gulch (Mulligan, 1966, p. 19). Little tin is found in Goodwin Creek above the mouth of Goodwin Gulch. Three USBM churn-drill holes (Heide and Sanford, 1948) further downstream below the mouth of Wales Creek (not located on existing maps, see location above), identify another 1000 foot-long pay streak which averages one pound tin per cubic yard (Mulligan, 1966, p. 19). Wales Creek is reported to have yielded several hundred pounds of tin-bearing concentrate to hand mining of a small depression at the headwater forks (Mulligan, 1966, p. 21).
Workings: Primarily widely spaced USBM churn-drill holes.
Age: Quaternary
Production: Very minor; perhaps some near the mouth of Goodwin Gulch and several hundred pounds of tin-bearing concentrate from the headwater forks of Wales Creek.
Reserves: Not defined; a narrow pay streak has been locally identified.

Commodities (Major) - Sn
Development Status: Yes
Deposit Model: Alluvial tin placer (Cox and Singer, 1986; model 39e)
