A family member cooked some up last week. He steamed them first then cooked in pan with leaks and butter. They were very good, like restaurant good. I don't know what they look like but they are around here in dubois area.
Park ranger told us over the summer it is in cook forest. They are fighting it with the largest hemlocks by basically pouring pesticide around the base so it gets into the root system. They can't fight the bugs with dropping pesticide from helicopter so it's very labor intensive. All the other hemlocks are on their own.
