|Location and accuracy||Placer gold prospects occur along the upper part of Kiagna River. The location arbitrarily chosen to represent these prospects is on the river at the mouth of Martin Creek, a west tributary. The location is probably only accurate to within several miles. Cobb (1972 [MF 373]; 1979 [OF 79-1246]) included information about these prospects under the name 'Kiagna River.'|
Geologic descriptionMoffit (1916, 1918) reported that placer gold was known along upper parts of Kiagna River since about 1904. A small stampede to the area occurred in 1914, but little gold was probably produced. Valley glaciers have occupied the Kiagna River drainage. Bedrock in the area mostly consists of Paleozoic and Mesozoic metasedimentary and plutonic rocks (Hudson and Plafker, 1982).
