Description
Photo 3: View toward the east illustrating the abundance of light gray biotite granite on Squirrel Island (Dsi).

These rocks, crystallized from silica-rich magma deep beneath Earth’s surface, are composed primarily of light-colored quartz and feldspar, and lesser amounts of dark-colored mica (biotite). Southern coast of Squirrel Island, Southport.
