If you drive up into the mountains or through the canyons, you may notice signs that say “Watch for falling rocks.” We have recently received a CD with a lot of interesting reports on the geology, geologic hazards and history along the I-70 corridor (which you might not guess from the title): “Field Trips” from the 1st North American Landslide Conference, June 2007. There are pictures and diagrams showing weak areas in the slopes and sections with landslide potential. The reports include geologic maps, and discuss the formations in the area. Also included is a paper on Colorado Wine Country, how the geology, soils and climate affect the wines in the region. The CD is a special publication from the Colorado Geological Survey. It was distributed to our state depository libraries, and is also available to check out from the Colorado State Publications Library.
