The Elden Pueblo is located on Highway 89 on the northern edge of Flagstaff. It is a half mile self guided walking tour that is well worth the visit! There are several foundations of pueblo structures and an informative pamphlet telling you about them. Admission is free!
This is a sketch of how the pueblos would have looked. Entry into the stone pueblos was through the stick, grass, and mud roofs with the exception of some doorways on the upper level. Some doorways were found on the lower level, but they had been rocked in as part of the wall. It appears that the inhabitants discovered first floor doorways were a bad idea and progressed to entrances through the rooftops accessible only by ladders! It didn't say, but I wonder if the exterior ladder was pulled onto the roofs at night!
These were available to throw at targets, but we didn't get a chance to try our skill with them. The Elden Pueblo site was an easy, relaxing, educational, and fun walk of no more than 30 minutes to an hour. Be sure to take the time to check it our when you're in Flagstaff!
