Lyman Glacier is in Wenatchee National Forest in the U.S. state of Washington and is just northeast of Chiwawa Mountain.[2] Between the years 1890 and 2008, Lyman Glacier has retreated 1,310 m (4,300 ft) and lost 86 percent of its area, a reduction in its surface from 1.41 to .02 km2 (0.5444 to 0.0077 sq mi).[3] Lyman Glacier terminates at a proglacial lake and a series of smaller lakes as well as a pronounced terminal moraine indicate where the glacier once extended to.
