Otolith from a Bloater Chub used for age analysis
An otolith, sometimes called “earstone,” of a bloater, a small prey fish in the Great Lakes. Fishery scientists interpret the age of bloater and other fishes by counting annual growth rings on their otoliths.

Location of Otolith Inside Alewife
Otoliths are located directly behind the brain of bony fishes. On the young alewife shown here, the approximate location of the otoliths is noted with a yellow arrow.

New outcrops make good geology
This aerial view of the western part of Kīlauea Volcano's caldera was taken on August 6, 2018. The down-dropped block is faulted about 120 m (400 feet) below the caldera floor. Many 19th-century lava flows are exposed in the fault scarps. Halema‘uma‘u (not visible) is to the left of this photo. USGS photo by D.Swanson.

Former site of San Clemente Dam, Carmel River
San Clemente Dam was a 106-foot-high concrete arch dam that was located approximately 18.5 miles from the Pacific Ocean on the Carmel River. It was built in 1921 to create a reservoir to support the growing residential, agricultural, and tourism-related development.

Thermal feature along Ferris Fork near Bechler River, Yellowstone
Thermal feature along Ferris Fork near Bechler River, YellowstoneAn unnamed but charismatic thermal feature alongside Ferris Fork, near the Bechler River. The center of the pool is roiling with gas bubbles, but not boiling! The pool is only about 180 degrees F (81 degrees C), and all the gas is bubbling up from underground.
