The layout of Kleckner Oasis is a bunch of hills with a lot of valleys in between them. The valleys are host to some big cottonwoods(Populus deltoides).
This Eastern Cottonwood tree is over 16 feet in circumference, and as with most of these giants, has been hit by lightning in years past. Definitely stay away from these trees during thunderstorms, maybe also when it is windy. Some dead branches up high that are bigger than a human, are waiting to crash down.
