The deep and steep-walled Rio Grande gorge in northern New Mexico is remarkable. This large gash is developing because the Earth’s crust is pulling apart, creating a linear depression, or rift, that provides a convenient location for a large river to develop. On a recent trip I admired the river -- and desert bighorn sheep.
Volcano-watchers have had lots of excitement lately with the ongoing eruptions on the Reykjavik Peninsula in Iceland and Soufriere, on the West Indies island of Saint Vincent. So far both eruptions are fairly small. Colorful graphic representations of the relative sizes of volcanic eruptions are intriguing, although variability in natural events confounds human attempts to assign neat boxes or bubbles to these phenomena.
The ghosts of famous artists–and of several hundred dinosaurs who perished in disastrous floods–could be roaming the landscape of Ghost Ranch in north-central New Mexico. This high desert region with steep cliffs and colorful rocks has a long and rich history. Finally visiting Ghost Ranch during a recent road trip, I was captivated by the beauty and the history of the place.
California encompasses tremendous diversity, and this includes rocks of virtually every age, reflecting a long and dynamic geologic history. I'm fond of all types of rock, but my favorites are shales, sandstones and limestones that preserve evidence of ancient plant and animal life. The older the fossils, the more interesting.
Traveling to explore new landscapes–and returning to favorite ones–will be one of many joys gradually reopening to us after the months of just-stay-at-home guidelines. This winter I’ve been planning future road trips in California and beyond, and I can recommend some great books about the geology in the western states.
