Inventory Map

Find the location and details of each of the erratics by clicking on the colored dots on the Washington map. Details like size, location, and composition are listed for each of the erratics. Most of these erratics have specific owners, so it is important to read the owner’s comments listed with each.

Please Note: This is an initial draft of all the information; I will be attempting to visit/revisit many of these sites to verify that the information is all correct and that the “unknowns” are filled in. However, if you know an unknown fact or see an incorrect entry, please let me know and I will change it immediately. In addition, if you have an erratic report that I failed to put on the map, please visit our “add an erratic” page. Thank you so much!
