Erigeron glacialis is native to the mountains of western North America, including Cascades, the Sierra Nevada, and the Rocky Mountains.^[5] It has been found from Alaska and Yukon south as far as California, Arizona, and New Mexico.^[6] In the Sierra Nevada, it may be found with mixed coniferous and upper montane vegetation types, and in the alpine zone to 11,200 feet (3,400 m).^[4]^[3]

Erigeron glacialis is a perennial herb up to 70 cm (28 inches) tall, with a thick taproot and spreading by means of underground rhizomes.
