Asteroid and comet impact events are known to cause profound disruption to surface ecosystems. The aseptic collection of samples throughout a km-deep set of cores recovered from the deep subsurface of the Chesapeake Bay impact structure has allowed the study of the subsurface biosphere in a region disrupted by an impactor. Microbiological enumerations suggest the presence of three major. Fig. A simple impact crater. Barringer Meteor Crater (Arizona), a young, well-preserved, and well-known impact crater, km in diameter, has become the type example for small, bowl-shaped impact craters of the simple type. The crater was formed ab
At the very center of the crater, a series of rugged mountainous peaks towers 1 kilometer or more above the basin floor. While seismic profiles also exhibit plausible evidence for most of the depositional units predicted to fill the Chesapeake Bay crater, deep coring was required to be sure. A number of Native American legends chronicle the lake’s formation; in one, a spirit named Llao was peering through a great hole left in the top of the ancient Moyaina, or “big mountain” by Gmo’Kam’c, the creator, at the time he made all the trees and rivers in the land.
Meteor Crater is kilometers ( miles) in diameter and meters ( feet) deep. The Chicxulub Crater, on Mexico’s Yucatan Peninsula, was most likely created by a comet or asteroid that hit Earth about 65 million years ago. The crater is kilometers ( miles) wide and meters (3, feet) deep. Crater Lake covers 21 square miles and measures up to 1, feet in depth. This makes it the deepest lake in the United States and the 3rd deepest in the world. The lake is so deep, that it was long rumored to be bottomless.

Theme and Variation
The Deep Bay structure is a circular feature 11 km in diameter, at the south end of Reindeer Lake. The crater is defined by a m deep circular bay in a lake which elsewhere averages only m in depth. The shape and depth of the bay contrast sharply with other lakes in the area.
Deep Bay is a bay near the south-western tip of Reindeer Lake in Saskatchewan, Canada. The bay is strikingly circular and very deep ( m) in an otherwise irregular and shallow lake. It is the deepest body of water in Saskatchewan.
Sweet, A. R., Applied research report on 4 mid Cretaceous samples from boreholes in the Deep Bay crater, Northern Saskatshewan, Paleontological Report, Department of Natural Resources Canada 3-ARS Deep Bay is a bay near the south-western tip of Reindeer Lake in Saskatchewan, Canada.
The bay is strikingly circular and very deep ( m) in an otherwise irregular and shallow lake. It is the deepest body of water in Saskatchewan. The bay was formed in a 13 km wide impact crater.
Deep Bay, Saskatchewan, Canada. This crater consists of a near-circular bay, about 5 kilometers wide and meters deep, in the otherwise shallow Reindeer Lake. Such deep circular lakes are unusual in this region, which is dominated by the shallow gouging of glacial erosion. The circular shoreline, at a diameter of 11 kilometers, is partially.
Located 90 km straight east of the Deep Bay crater in the Saskatchewan region, the Gow crater is roughly circular lake with the prominent Calder Island, km. An impact crater in Saskatchewan, Canada (56° 24' N, ° 59' W), formed about million years ago in Precambrian metamorphic crystalline rocks, that is visible as a near-circular bay, about 5 kilometers wide and meters deep, in the otherwise shallow Reindeer Lake.
The circular shoreline, at a diameter of 11 kilometers, is partially surrounded by a ridge with heights to meters. These properties are similar to those of impact craters of comparable size such as Deep Bay, Saskatchewan [2, 3]. In addition, glacial float on the down-glaciation (southern) shores of the lake includes considerable numbers of boulders of friable breccias and glassy rocks (mean density g crri 3) containing abundant indications of shock.

Located beneath the mouth of the Chesapeake Bay running from underneath the tip of the Delmarva Peninsula (near present-day Cape Charles, Virginia), across the Bay to Norfolk, Virginia, the roughly circular crater is twice the size of Rhode Island (2, sq mi [6, sq km]) and nearly as deep as the Grand Canyon ( mi [ km] deep).
"The explosion in the port left a crater 43 meters deep," the Lebanese security official told AFP, citing assessments by French experts working in the disaster area. The crater is much larger than the one left by the enormous blast in that killed former prime minister Rafic Hariri, which measured 10 metres across and two metres deep.
In the United States, the scientific community and the public, as well, were startled to learn, inthat the largest impact structure in this country had been detected beneath Virginia's portion of the Chesapeake Bay.
Seismic surveys and deep coring revealed a huge crater, 85 kilometers in diameter and more than a kilometer deep. The steam generated would create a heat shield allowing the meteor to penetrate the atmosphere and protect it from being destroyed. I believe that the Crater (s) of Hudson bay and all across Canada are the evidence of what caused the Laurentide ice fields.
A single event. All Glacial movement radiates from Hudson Bay which supports my theory. Formed roughly 35 million years ago, the meteor that crashed into what is now known as the Chesapeake Bay hollowed out a mile-wide crater on the Northern Atlantic floor, entrapping a.

I now can see the effect that the remains of the crater impact has had on my home area. As I drive from Gloucester to Mathews there is a very clear escarpment that follows the rim of the ancient crater which one can observe for several s: DEEP BAY Deep Bay Crater magnetic variations (Sander ).
Several mechanisms related to impacts may radically change the magnetic properties of target rocks. Peak pressures in autochthonous rocks may reach ~30 GPa at impact, which is sufficient to produce. Deep Bay. Deep Bay is a real place and she’s a beauty. Situated on the North Shore of Bermuda lies a small bay with turquoise ocean as far as the eye can see to the north and cliffs on all other sides.

The impact occurred southwest of what is now Johannesburg, South Africa, and temporarily made a kilometer-deep and kilometer-wide dent in the surface.
Almost immediately after impact, the crater widened and shallowed as the rock below started to rebound and the walls collapsed.
