United States Meteorite Impact Craters

Des Plaines Crater, Illinois, is about 8km in diameter.  It is a buried structure with no surface expression.  The structure is less than 280 million years old.  It was discovered and described through drilling.

Evidence of Impact Origin

The impact origin of each location listed on this website has been supported by unambiguous diagnostic evidence of hypervelocity impact that has been reported in a scientific (usually peer reviewed) context.  Without such evidence, a geological structure is not a confirmed impact crater.  This section, which is included for each crater on this website, is not an exhaustive list of such published evidence, but is meant to demonstrate that appropriate work has been done for each listing.

• shatter cones
• planar deformation features in quartz (described)

Other significant evidence: morphology (from well logs and seismic), breccia.

Introduction

An impact origin for the Des Plaines structure was first proposed in Emrich and Bergstrom (1962).  The publication contains a general map of the structure, contextual maps of the region, a cross section, rough boughuer gravity map, and discussion of the available observations in terms of the emergent science of impact craters.  It renames the structure as a cryptoexplosion rather than cryptovolcanic structure.  The paper also records a central uplift displacement of about 600 to 900 vertical feet, a diameter of about 5 1/2  miles, and other general morphometrics.  An additional brief description of the structure and a more detailed description of its regional context can be found in Willman, 1971.

An impact origin was confirmed with the discovery of shatter cones and report of shock metamorphic features in quartz grains, reported by McHone et al., in abstracts from 1986 and 1987.  More details may be present in Peterson, 1989, and better maps may exist in a Master's Thesis published in 1974 by Langan.
