	Lunar Impact Crater Geology and Structure (Site not responding. Last check: 2007-11-03)
		Bessel Crater, 16 kilometers in diameter and 2 kilometers deep, is an example of a transitional crater between simple and complex craters.
		The terraces and slump blocks on the inside of the crater rim and the relatively flat floor are both typical of large lunar craters.
		Copernicus Crater, 93 kilometers in diameter, is one of the youngest and freshest impact craters on the nearside of the Moon.

	Geotimes - January 2004 - Coring the Chesapeake Bay Impact Crater
		Its outer rim is a steep sedimentary fault scarp, with structural relief of 300 meters on the west and 500 meters on the east (downdip).
		Above the megablocks is a clast-supported breccia, composed mainly of debris from the tops of the megablocks, crater walls and the surrounding seafloor, scoured by the marine water column as it surged back into the excavation.
		The buried southern rim of the crater is marked at the surface by the southern shore of Chesapeake Bay and by the parallel slope of the Diamond Springs scarp.

	JPL.NASA.GOV: News Releases
		Operators of NASA's Mars Exploration Rover Opportunity have determined that a proposed route eastward out of "Endurance Crater" is not passable, so the rover will backtrack to leave the crater by a southward route, perhaps by retracing its entry path.
		Opportunity entered the stadium-size crater on June 8 at a site called "Karatepe" along the crater's southern rim.
		Inside the crater, it has found and examined multiple layers of rocks that show evidence of a wet environment in the area's distant past.

	Bandera Crater (Site not responding. Last check: 2007-11-03)
		Bandera Crater is the largest volcanic cinder cone in the region.
		Over time, erosion and gravity take their toll on the crater and it is slowly filling up as cinders and rocks fall down into it.
		The back wall was formed in the early days when ancient Indians and early settlers mined the ice.

	Moons Questions
		By comparing the density of craters (for example, number of craters per million square miles) on different parts of the Moon’s surface with the ages of the rocks found in those regions, we can determine that most of the craters formed very early in the history of the Moon.
		The material expelled from the crater is hurled upward, and then falls back to the surface to form a raised ejecta blanket surrounding the new crater.
		Bedrock under and around the crater is shattered, and the rock closest to the crater may even be melted by the energy released in the explosion.

	Meditation Along Meteor Crater Rim
		Sometime back I was along an isolated section of the Meteor Crater rim in Arizona practicing a deep meditation method sometimes refered to as Jishu-zammi, Samadhi of Self Mastery, a variant of sorts on Dogen Zenji's Shikantaza.
		The crater is an immense impact-hole pounded out of the Earth thousands of years ago by a huge bolide that crashed through the sky...and something about the place holds a deep fascination for me since early childhood.
		Coming back in time now to this visit, as I sat in the remnant remains of one of the ancient Pit Houses dating to the twelve century along the slope of the south rim, without saying a word, a person came up and joined me in meditation for a while.

		Sally Crater stated that he was murdered “because of something sinister connected to politics”.

		One possibility is that the bright material is similar in composition to the rocks in Eagle Crater's outcrop and the surrounding darker material is what's referred to as "lag deposit," or erosional remnants, which are much harder and more difficult to wear away.
		The backshell and parachute that helped protect the rover and deliver it safely to the surface of Mars are also visible near the horizon, at the left of the image.

	Molokini Crater (Site not responding. Last check: 2007-11-03)
		Molokini Crater is approximately 4 miles off the South Maui Coastline in the Makena area and is a Marine Life Conservation District.
		In my opinion the best diving at Molokini is outside the crater at "Reef's End" and the "Back Wall." Depths can reach over 300 feet so one must closely monitor their depth gauge.
		Another option is to start inside the crater, scuba along the outside reef, and continue on around the Back Wall getting picked up by the boat wherever you surface.

		Back at the boiler, I made sure the valve at the y-joint was redirected to control the lever I was about to experiment with.

		The opening acts of Na Leo and Yvonne Elliman performed admirably with the Honolulu Symphony, but to a sparse crowd, as most of the attendees were either enjoying the beer garden and food booths or had yet to be bused in.
		And that is how the fans felt filing onto the buses to take them back to their civilized lives; you can't put a price on the past.

	Mars rover to take risky trip into crater - Return to the Red Planet - MSNBC.com (Site not responding. Last check: 2007-11-03)
		The potential scientific value of exploring Endurance Crater outweighs the risk that the six-wheeled rover may not be able to drive back up its inner slopes, mission officials said.
		Back in January, at the very beginning of its mission, Opportunity landed in a smaller depression known as Eagle Crater and found evidence of a vanished salty sea within the layered rock there.
		Endurance Crater is much deeper, and may shed additional light on the question of how long liquid water persisted on Mars.

	Nevada - Lunar Crater National Natural Landmark
		The crater is designated a National Natural Landmark, one of six in Nevada, and is situated 75 miles east of Tonopah near the center of the state.
		It is geologically termed a 'maar', the name given to a shallow, broad crater formed by explosive eruptions close to ground level, usually caused by heating of subterranean water.
		Access: One unpaved road (the Lunar Crater Back Country Byway) passes by the crater, and the usual approach is from the north, starting from US 6.

		The images the mother ship spacecraft sent back are stunning, showing a bright curtain of materials surrounding the impact site, and giving the science team an Independence Day to remember.
		But as the probe got closer, it began to discern the heart of the comet — its nucleus — and sent back pictures in real-time of what appeared to be a pear-like structure.
		A preliminary analysis of the data indicate that the upper surface of the comet may be fluffy, or highly porous.

		Spirit also sent back a “you are here” picture of Earth as seen in a Martian sunrise, as well as a bright sky streak that may well have been caused by the glint of a nearly 30-year-old spacecraft as it passed overhead.
		Last week, scientists released compelling evidence that the crater where Opportunity landed may once have been “drenched” in water, but the evidence from the Spirit site is sparser.
		However, he said it was far too early to determine whether the crater’s geologic makeup was intriguing enough to warrant a trip inside.
