UA Professor Alison Hawthorne Deming is a highly regarded poet and essayist who, at most every turn, works to translate matters of science and nature into poetry and prose.

Consider your tactile and sensory reality.

For some, the sound of birds stirring awake with the dawn of day, the plop fish make when hitting water, the strong scent of sagebrush and moist pine or the feel of soft soil underfoot are all foreign.

Given the tremendous rate of scientific and technological advancements at a time when people are increasing moving to urban areas, the bond between humans and the natural world seems, at times – and is, indeed, for some – strained.

But the association is not foregone. (more…)

Landslides Linked to Plate Tectonics Create the Steepest Mountain Terrain

Some of the steepest mountain slopes in the world got that way because of the interplay between terrain uplift associated with plate tectonics and powerful streams cutting into hillsides, leading to erosion in the form of large landslides, new research shows.

The work, presented online May 27 in Nature Geoscience, shows that once the angle of a slope exceeds 30 degrees – whether from uplift, a rushing stream carving away the bottom of the slope or a combination of the two – landslide erosion increases significantly until the hillside stabilizes.

“I think the formation of these landscapes could apply to any steep mountain terrain in the world,” said lead author Isaac Larsen, a University of Washington doctoral student in Earth and space sciences. (more…)
