Background
Rugged pinnacles form the summit of the deeply eroded Isanotski stratovolcano, locally known as Ragged Jack. Isanotski is at the center of an E-W-trending group of three volcanoes on eastern Unimak Island. Four poorly documented historical eruptions were noted in the 18th and 19th centuries. However, Miller et al. (1998) considered that some or all of these eruptions could have been from neighboring Shishaldin volcano and that historical eruptions of Isanotski must be considered unlikely, given the extreme degree of erosional dissection.---

Mentre Shishaldin è un superbo esempio di stratovulcano giovane e simmetrico, il molto più antico Isanotski è irregolare e profondamente eroso. (Photo: marcofulle)
