Sense of Place

Map of Tucson
"Go my children, burn your books. Buy yourselves stout shoes, get away to the mountains, the deserts, and the deepest recesses of the earth. Mark well the distinction between animals, the differences among plants, the various kinds of minerals. In this way, and no other, will you arrive at a knowledge of things, and of their properties."
—Peter Severinus, AD 1571

Description: Students are introduced to the geology and ecology of Tucson and surrounding mountain ranges, including interactions between past and present societies with desert and forest environments. Four Saturday field trips (one per month) are scheduled during the semester, each emphasizing a particular region with unique geological and biological aspects. This is a first-year colloquium course, but any UA student can enroll.

A Tuesday evening class meeting will take place prior to each Saturday field trip.
