The descriptions and bibliographies listed on this page represent structures that may turn out to be impact craters, and which have been previously described in the literature. This section is not the primary focus of this website, and may remain substantially less complete and up to date than other sections. Please submit improved descriptions, photographs, additional references for articles related to the listed structures, or any other structures not described here, to firstname.lastname@example.org This website will only be as complete and useful as we make it through community effort. If you have located a possible impact structure that is not represented here, please let me know the specific GPS coordinates and approximate diameter, and I will add these also, though they will be placed on the 'Unpublished Possibles' page. Listed in alphabetical order, with bibliographies.
Bee Bluff, Texas (also known as Uvalde or Lyles Ranch), is a possible meteorite impact crater located in Zavala County, Texas. It is variously reported as between about 1.6 and 2.5 km in diameter.

Refuted Impact Structures:
The Avon Structure
The Avon structure, one of the sites originally associated with the 38th parallel lineament hypothesis, is known today to consist of a cluster of volcanic dikes and filled vents, called diatremes. This site did not originate as a meteorite impact.
