From Wood and Kienle (1990) [1] : "Roundtop is an eroded and glaciated stratovolcano, located ~13 km southwest of the village of False Pass. In the 1930's warm springs were found on its slopes. Recent field study indicates the presence of Holocene pyroclastic flows and a group of domes south of Roundtop, as well as a thick silicic pre-Holocene flow."

Name Origin

This feature was reported as "Round Top" by the U.S. Coast and Geodetic Survey in 1902, and called "Dome" by J.F. Moser, U.S. Navy, in 1897 (Orth, 1971).
