This picture was taken at the Lava Beds National Monument. My husband and I were exploring Sentinel Cave. This cave has two entrances. As we were walking with our lanterns we saw a light ahead and thought we were nearing the second cave entrance. When we walked around a bend and cleared some rocks this is what we saw. The light was streaming through a natural opening in the cave. It was an amazing sight! We plan on returning next year to share this beautiful park with our grandson!
