Mark Leach, will be featured at the June meeting of the Saint Louis Astronomical Society. He serves as the Restoration & Research Coordinator of the Blake Mound & Cave Site and as a long-standing trustee of the Missouri Archaeological Society.

This month's meeting will return to being held IN PERSON at McDonnell Hall, Room 162, Washington University in St. Louis, and via Zoom.

Nearly 1,000 years ago, a vibrant Cahokian community filled the entire Chesterfield Valley. Like Illinois' Cahokia, this civic, ceremonial, and market center was precisely planned and constructed to reflect important celestial alignments of the sun, moon, and Milky Way. Though only a small portion of the community has been professionally studied, over 100,000 artifacts have been discovered. Included are exotic materials from the Great Lakes and the Gulf of Mexico. A massive Calendar of the Sun, involving three temples and two earthen pyramids, stretched 3.56 miles across the valley. Cahokia in Chesterfield has been the focus of professional archaeological research for over 70 years. Research is ongoing and the heart of the ancient city lies well preserved under six feet of flood deposited soil.
