Post glacial landscape, New Zealand

Like many areas in the world glaciers have sculptured and carved the landscapes we see today. They all scrape away the softer rock and sediment beneath them. As the ice melts during a “retreat”, it will drop rocks, sediment, and debris once carried on the surface of the ice. Unlike a river, glaciers only drop their cargo when they melt. In this case further “weathering” has also occurred. Forces such as rain water run off and frost heave of soils/clays come into play. Due to altitude induced coldness, not much grows. But there is evidence of these areas in New Zealand once being home to totara forests. The cover in this photo is a resident tall grass known as snow grass. Also known as red tussock.
