"The photo above showing a huge outcrop of breccia was taken in Fall Canyon at Death Valley National Park, California. Breccia typically forms when angular fragments (over 2mm in diameter) of rock accumulate in streambeds and alluvial fans, for instance. The pieces become bound by mineral cement or are fixed by much smaller particles that fill the spaces between the angular pieces. A debris flow is one condition where binding of the fragments can happen. Another such condition is a meteor impact crater. Breccia is similar to conglomerate, but in conglomerate the fragments are more rounded, indicating that they've traveled further (are more eroded) before cementation occurs."

"What a gorgeous Native Gold !
It's completely crystalline with flattened dendritic crystal growth to
the right and dodecahedrons and trigons crystals to the left.
When the specimen was forming, a small seam probably opened up in the Quartz matrix and allowed for the development of larger, unflattened crystals. on both the front and back side of the specimen. The flattened crystalline growth to the right is pure dendritic, displaying beautiful herringbone patterns throughout.
From the Eagle's Nest Mine, Placer County, California.
Measures 6.1 cm by 6.7 cm in size."

"It's 369 feet high. That's about twice the size of the Statue of Liberty (minus the foundation). ...The people who discovered it have never revealed its true location, which is somewhere in Humboldt Redwoods State Park. And though it has a nickname, "Stratosphere Giant," it is no longer the giant. It's been trumped.

The tallest of the tall is 379 feet 4 inches, 10 feet taller than the Giant. It's now called "Hyperion.""

"The photo above shows a layer of salt formed on the surface of Searles Lake in California. Salt, yes, but with an interesting formation process. It greatly resembles three-dimensional models of topographic maps. The process involves the evaporation of the brine to create the crusts of salts, but with an ever-decreasing level of brine. The unique aspect of this formation is that the brine level apparently dropped in discrete stages. This allowed a ledge of salt to be formed distinct from those above and below. The somewhat regular spacing of the ledges (which so closely resembles those of contour lines) must have formed over daily cycles of evaporation during a time in which conditions of temperature and evaporation rates were very constant. Counting the ledges indicates this period of constancy to be about two weeks."

"This astronaut photograph highlights the mostly dry bed of Owens Lake, located in the Owens River Valley between the Inyo Mountains and the Sierra Nevada. Shallow groundwater, springs, and seeps support minor wetlands and a central brine pool. Two bright red areas along the margins of the brine pool indicate the presence of halophilic (salt-loving) organisms known as archaeans. Gray and white materials within the lake bed are exposed sediments and salt crusts. The nearby towns of Olancha and Lone Pine are marked by the presence of green vegetation, indicating a more constant availability of water."

"The Sacramento River Delta is the main drainage for the entire state of California, funneling rain and snowmelt from the Sierra Nevada mountains toward the San Francisco Bay. This inverted delta, where the channeling and river braiding occurs before the river reaches its outlet, has created a fertile agricultural area. Water is pumped through canals to irrigate the fields and serve many cities in the Central Valley.

The state depends on the food grown here, but pumping so much water for crops has threatened fish populations, such as the delta smelt, and long-fought legal battles continue over water rights. This image, taken by the Landsat-7 satellite, shows the confluence of the Sacramento (top) and San Joaquin (center) Rivers and the city of Antioch (bottom left)."
