Tucson Mts.

Map of Tucson Mts

The Tucson Mts. is one of the favorite natural-cultural history short trips around Tucson. It includes everything: geology, climate, desert plants and ecology, cultures, pollination, pack rats, etc.

Rock Jumble

A stop on Trail's End has about 10 different kinds of rocks in one place. How so much variety in geology?

Giant Saguaro

We'll check out saguaro quite closely, including right next to the spines. Maybe we'll get lucky and see a bobcat "treed" up one of the giants.

Recent hard freeze likely will be death knell for many weaker saguaros: This 2011 AZ Daily Star article notes potential mortality of saguaro due to the cold snap early February 2011.

Gate's Pass

Gate's Pass has volcanic rock of the Tucson Mt. Caldera as well as outstanding vistas of more saguaro and more Basin and Range.

Petroglyph Artwork

Signal Hill is aptly named, as it has many ancient petroglyphs, i.e., images tapped into rocks. Who? Why? How long ago? What do they mean?
