Greetings Everyone,
I am announcing this discovery as a long time contributor to the Colorado Prospector Forum and want to make sure that other members have access to this information. After initiating a research effort in 2005, I have been able to collect substantial evidence to support a double meteorite impact located in Custer County, Colorado. The Westcliffe Crater is the larger structure while the Silver Cliff Crater is smaller and both are named for the towns nearby. All my work has been done independently and at my own cost. This previously unrecognized double crater structure is paired with my discovery of the Gunnison Crater. All 3 impacts occurred 360 to 375 million years ago. These impact craters are further evidence supporting the Tonko Lineament that recognizes the serial impacts across the United States aligning on the 38th Parallel. The crater chain and associated fish fossil records I have researched indicate a Devonian mass extinction event where 70% of life on our planet was eliminated. Along with hyper-velocity geologic evidence in the target zone, I have also recovered two meteorite types that are in the early process of classification.

You are of course free to misuse the term lineament to define what you believe is a series of impacts similar to the Shoemaker-Levy 9.
Perhaps Geomatt will weigh in with his opinion on its usage. Merely connecting dots along the 38th parallel does not make it a lineament. |

Merely connecting dots along the 38th parallel does not make it a lineament. Dear Mr. Kooper and Geomatt: There are many geologists and other researches that also freely use term the lineament when referencing the impact craters along the line of latitude 38 degrees North. Here's a great example from the 51st Annual Meeting of the Association of Missouri Geologists on page 15 back in 2004; "From east to west the disturbances are Hicks dome, Avon, Furnace Creek, Crooked Creek, Hazelgreen, Decaturville, Weaubleau, and Rose dome. This line of structures defines what has been called the “38th parallel lineament” because it closely approximates the 38th parallel line of latitude (Heyl, 1972)." Then again on page 21 it states; "Rampino and Volk (1996) and Rampino (1997) theorize that the individual structures along the 38th parallel lineament are the result of a single serial impact event, similar to the serial impact of the fragmented Comet Shoemaker-Levy 9 into Jupiter during 1994." Here's the link to that document... LINEAMENT USE IN DESCRIBING SERIAL IMPACT CRATERS Also, there is a good use of the term here as well...MORE LINEAMENT USE IN DESCRIBING SERIAL IMPACT CRATERS The original series of depressions and deformation structures was approximately 700 kilometers in length, following the 38th Parallel through Kansas, Missouri and Illinois. The Tonko Lineament is an extension of the 38th Parallel Lineament that more than triples the previous length to a total distance of 2367 kilometers, through Colorado, Utah and into Nevada. Anyone that visits the craters I've discovered should bring dilute hydrochloric acid for field testing of carbonate rocks at those impact sites. That will help sort out specimens from "the common rock types of the valley that could be easily mistaken for impact related rocks (tuffs, breccias, rhyolites)" that Geomatt is concerned with. Putting a couple of drops on the impact breccia will show vigorous bubbling. I hope this helps everyone better understand this matter.
