371. Canyon de Chelly / June 15, 1933. Boundaries of the monument have not been located, although specified. A road leads along the top of the canyon but none up the canyon bed. We drove up the sandy bed of the way in a Ford with air wheels. This mode of locomotion seems quite satisfactory over the sand. It was agreed by all of us there that no road should ever be constructed up the canyon floor, that people should be transported by a supervised fleet of air-wheeled sport cars, leaving their own cars outside unless they had proper tires. This would insure preservation of the primitive state, & prohibit rifling of the ruins. The area is suitable for wild life development. However the few forms such as birds & reptiles are interesting to the tourist & add to the pleasure of a trip. The white palace needs protection from undercutting by the stream. At least half the lower ruin has already been swept away. A low brush & stake buffer about 12"-15" high has been installed but is insufficient. Most of the valley floor is sandy stream bed.
