In the mid 1960's, Lathrop Glacier was discovered on Mt. Thielsen on its north side. One can not see the glacier from the PCT even though it snakes right below the glacier's cirque. Two couloirs fed the glacier ice down to its moraine. We found no glacial ice on our visit and only glacially smoothed bedrock where ice used to flow in the couloirs. The stream coming out of the basin was void of glacial flour - you could drink the water. The last known photograph of ice in the couloir was in 2007. Lathrop disappeared completely sometime after that. Our first funeral needs to be held for this recent glacier passing.
