In Big Bend National Park, TX, take a short hike out from Grapevine Hills Road and you'll find this remarkable rock formation. Imaged in July 2005.
Full of wonder..
too close to this one!
Thanks for looking, Marksoltan. I do have a photo of my son (cdoiron on SP) sitting under it enjoying a little lunch, but, you're right that it does look ready to fall any moment! --mark d.
