I have a hunger for Geology here in the Glacial world of Montana. Most of out formations here have been carved by the receding glaciers and Lake Missoula run offs. I visited a large rock the size of a house over 300 miles down the Columbia from the Ice dam breaking in Idaho. Quite impressive.
Back to the questions. Does anyone know the proper knappweed eradication protocol. My newly aquired 8 acres of meadow has knappweed on it.
