Desert Speaks

Into The Swell: Utah's High Desert

Utah's San Rafael Swell is one of the most remote and least-visited wonders of the desert southwest. Host David Yetman and his brother, Geologist Dick Yetman, camp out and explore the geology and vegetation of this intimidating stretch of desert. They also trek through Utah's Little Grand Canyon to see the pictographs and petroglyphs that were created thousands of years ago.
