Impressions Of Nature: Majestic Wilderness: Red Bluff

Glacier Bay, Alaska - Red colored cliff-face near Margerie Glacier. Red Bluff takes its name from the bare, reddish-brown weathered surface of the igneous rocks that crop out on steep slopes and rise from the shore. The color is the result of oxidation of iron and magnesium minerals over time. Glacial ice is seen floating in the foreground.
