I didn't measure the ice, but it appeared to be about 15" thick and was good solid ice. A pressure ridge is as you described it, where a crack is formed in the ice and the ice stacks up on the crack. There is one pressure ridge that went on for miles on the east side of Bear Lake. We didn't have any problems crossing it, but would step entirely over the ridge. I believe that they stepped right in the center of the ridge. There are some places along that ridge where there is even a few inches of open water. Also, one must be aware of those bubbling springs at Bear Lake, where there is often a large pool of open water, or sometimes they are small, but still open.
