Arches: Fiery Furnace

However, this hole is indeed regarded as an arch. Arches have to have one dimension greater than three feet and light should also be visible on the other side. This one was named Crawl Through Arch. True to its name, three young ladies from our group were invited to crawl through to the other side.
