Continue on Thurston Lane to Guggenheim Hall, and note the Dawn Redwood, growing with western white pine, vine maple, and Douglas firs. You cannot help noticing it, for several features make it striking. Even in winter its swollen, reddish, buttressed trunk is unique. The summer foliage is delicate green, then turns orange or brown in fall. This native of China's eastern Szechuan and NW Hupeh is the only non-extinct deciduous redwood, and is famous for that reason, as well as for being an ornamental conifer wherever room allows--it grows 200 feet tall with trunks of corresponding thickness. This example probably dates from 1948.
