This shot of the footbridge was buried in a PowerPoint presentation that was sent to me a few years ago. It’s undated. Click on it to enlarge.
The photo above was taken from the west side of the canyon. Behind the photographer was a circular parking lot built around a small sandstone hill. The next photo shows the parking lot and the photo below it is an image I took today using Google Earth that shows the remnants of the circular parking area as it appears today. This temporary foot bridge spanned Glen Canyon and was located just upstream of Glen Canyon Dam.
Here’s the image I captured this morning on Google Earth showing how the parking area appears today.

From Google Earth. The horseshoe-shaped parking area is wrapped around the sandstone hill on the west side of the canyon. The spillways are visible at the bottom of the photo.
I’ve written other posts about the upper footbridge. To see them all, type “footbridge” in the search box at the top of the page.
Enjoy!
