Geologic descriptionRoehm (1947) investigated a report that in 1906 Val Klemm located a deposit of hematite on the beach in a small bight near High Point on Dall Island, and drove a 48-foot adit on it without reaching ore. The deposit was said to be 20 feet wide and could be traced for 2,000 feet up the mountainside, along a contact between limestone and greenstone. A sample contained 55.5 percent iron and 6 ounces of silver per ton. Roehm searched for the deposit in 1947 but did not find it. However, he did locate several hematite stringers along limestone-greenstone contacts in the area; the hematite is probably secondary after pyrite. The rocks in the area are schist, greenstone, and marble of the Wales Group of Late Proterozoic and Cambrian age (Eberlein and others, 1983; Brew, 1996).
