About 20 plus years ago wife, youngest son, myself, her brother, wife and daughter camp a couple day/nights there.
Storm came up river from north at night with thunder hitting on river and trees, mainly river. Sharp lighting.
Just sat and listen to the storm making its way to us.
Storm finally hit next to us at mid night. Had pop up and when thunder hit pop up would just shake. A lot of old, tall cotton wood and they start coming down with the thunder.
Lasted for some time and never been in a storm like that one with little rain. We were nervous, very loud. Brother was in a tent as was our son and their daughter. None of us under a cottonwood.
So if you go, do not camp under one of them there old and tall cottonwoods. Even the next day, now and then, a hugh branch would come trashing down off a tree. db
