The fascinating, awe inspiring, beer drinking world influenced by the earth's oldest science. This blog is about all things geology. Landmarks, minerals, sedimentary deposition, pretty pictures, and humor all fall into this category.
If you ever have questions dealing with your labs or you homeworks, ask. I will be able to find you the answer if I don't know it off the top of my head.
Also, send me links and I will give you credit.

Exfoliation dome. I forgot what peak we hiked to. Will have to research. Scanned from print.

Today I hung out in some conglomerate sandstone.

Ooh - here’s a strat column of the Capitol Reef.
The Waterpocket Fold defines Capitol Reef National Park. A nearly 100-mile long warp in the Earth’s crust, the Waterpocket Fold is a classic monocline: a regional fold with one very steep side in an area of otherwise nearly horizontal layers. A monocline is a “step-up” in the rock layers. The rock layers on the west side of the Waterpocket Fold have been lifted more than 7000 feet higher than the layers on the east. Major folds are almost always associated with underlying faults. The Waterpocket Fold formed between 50 and 70 million years ago when a major mountain building event in western North America, the Laramide Orogeny, reactivated an ancient buried fault. When the fault moved, the overlying rock layers were draped above the fault and formed a monocline.
More recent uplift of the entire Colorado Plateau and the resulting erosion has exposed this fold at the surface only within the last 15 to 20 million years. The name Waterpocket Fold reflects this ongoing erosion of the rock layers. “Waterpockets” are basins that form in many of the sandstone layers as they are eroded by water. These basins are common throughout the fold, thus giving it the name “Waterpocket Fold”. Erosion of the tilted rock layers continues today forming colorful cliffs, massive domes, soaring spires, stark monoliths, twisting canyons, and graceful arches. -

Crater Lake National Park - Oregon

Notes: These towering needle-like formations of rock, called fossil fumaroles, projecting from the Sand Creek Canyon floor, formed under sheets of volcanic pumice that preceded Mount Mazama’s collapse.

Wizard Island
Crater Lake National Park - Oregon
Yashica Mat 124G + Tmax 100 B&W negative film
Notes: Crater Lake partially fills a type of volcanic depression called a caldera that was formed by the collapse of a 12,000 ft (3,700 m) volcano known as Mount Mazama during an enormous eruption 7,700 years ago. Wizard Island is a volcanic cinder cone at the west end of the lake.
