Shastina
Shastina is a satellite cone of Mount Shasta. It is the second youngest of four overlapping volcanic cones which together form the most voluminous stratovolcano in the Cascade Range. At 12,335 feet (3,760 m), Shastina is taller than Mount Adams and would rank as the third highest volcano in the Cascades behind Mount Rainier and Shasta were it not nestled on the western flank of its higher neighbor. Shastina has a topographic prominence of over 450 ft (137 m) above the saddle connecting it with Shasta and easily exceeds the typical mountaineering standard of 300 feet (91 m) for a peak to qualify as an independent summit, yet most lists of Cascade volcanoes omit it nonetheless. The name "Shastina" is a diminutive of Shasta.
