The Park Service opened Square Tower on 1 September 2011 to limited visits of 10 people a day, three days a week, for six weeks, after being closed to the public for 75 years. We were in the first group to visit the site. After this limited opportunity, it will once again be closed to the public. It was an exceptional opportunity, and a trip we'll remember forever... Square Tower, as seen from the top of the canyon wall Debbie, beginning the trip, heading down the ladders, ropes, and narrow walkway across the canyon wall. It's WAY steeper than it looks! WAY steeper! And suddenly, you're there...the square tower for which the site is named rises majestically against the canyon wall. Click here for more photos of the site.
