Wells Creek is an impact crater located near Cumberland City, Tennessee. It is 12 kilometers (7.5 mi) in diameter and the age is estimated to be 200 ± 100 Ma (million years old), placing it in the Jurassic or a neighboring period. The crater is exposed to the surface. The center of the crater contains some of the finest shatter cones in the ...
The impact crater was formed approximately 360 million years ago as a shallow, saucer-shaped crater, 3.8 kilometres (2.4 mi) in diameter and about 150 metres (490 ft) deep. A large central hill, highly deformed rim strata, and a breccia lens 40 m (130 ft) in thickness were produced during formation.
The caldera is the enormous volcanic crater left from the last time Yellowstone experienced a giant eruption, 640,000 years ago. It covers an area about 30 by 45 miles .
(See Yellowstone Caldera map.) The Henry's Fork Caldera in Idaho was formed in an eruption of more than 280 km 3 (67 cu mi) 1.3 million years ago, and is the source of the Mesa Falls Tuff. [ 11 ] The Henry's Fork Caldera is nested inside of the Island Park Caldera and the calderas share a rim on the western side.

THERE'S A LOT on Yellowstone that’s absolutely not realistic, from murder pits to Beth’s whole general vibe, but where the actual act of ranching is concerned, the show actually seems to care ...
In 1900, he purchased the 8 Ranch in Guthrie, Texas, which became the nucleus of the present-day 6666 Ranch, followed by the Dixon Creek Ranch and later purchases which now all make up the ranch's ...
The EID lists fewer than ten such craters, and the largest in the last 100,000 years (100 ka) is the 4.5 km (2.8 mi) Rio Cuarto crater in Argentina. [2] However, there is some uncertainty regarding its origins [ 3 ] and age, with some sources giving it as < 10 ka [ 2 ] [ 4 ] while the EID gives a broader < 100 ka.
