Hi everyone- Does anyone know if there are any rappelling trips in the U.S. or Internationally to see fossils? also does anyone know if one can rappell down a cliff face to view the K-T boundary? I know its exposed and visible in Raton Basin, Raven Ridge and Trinidad Lake State Park but has anyone done rappelling on a fossil hunt? looking for a combo of fossil hunting, excavation and adventure! Any really super adventurous fossil hunting trips advise will be appreciated. thanks.
