Provisional Plant Checklist tabulation for McGee Peak, Shasta County.

Magee Peak, Shasta County is a subalpine summit situated about 20 miles northward from Mt. Lassen. MaGee Volcano exploded with a caldera eruption about 220kA ago. The peak has an extensive cirque on the north facing caldera wall and floor, and a blast zone to the north containing about 70 lakes of various sizes. McGee Peak (8549 ft) and Crater Peak (8683 ft) are the highest summits on the rim of the caldera. The region is designated as the Thousand Lakes wilderness, although about 930 lakes shy of that number.

This checklist is based on CCH specimen records and on my 1974-1975 collections: Frank W. Peirson collected on Magee Peak in 1932. A total of 318 specimen records are databased.

My intention is to complete a florula of the region, for comparison with nearby Lassen Volcanic National Park, which is well documented.
