Observations and Notes

2014:

The Hillsdale Site is located east of Cheyenne, Wyoming in a large agricultural field north of Highway 30, approximately 200 feet from a dirt county road. 

The field had just been planted, and we did not want to cross it without permission from the land owner.  We drove to the nearest farm house (approximately 1 mile away) and contacted the owner.  He told us that the owner of that portion of the field lived several miles away, and gave us directions how to get there.  We were able to locate the farm house, but unfortunately nobody was at home.

2018:

The field was really wet so we only flew the drone. From the drone photos we took it is easy to see that the tip of the arrow has been broken off. Probably the result of farming in the area. This arrow is in very poor condition.
