The following set of photos is of the Marmora Maze Caves in Ontario, Canada. This site has a large complex of interconnecting cave passages that head off in every direction imaginable. The passages range in size from walking passages to tight crawls, staying dry is impossible and getting wet is inevitable.
Some very small formations were present in the passages, but its the ice formations in winter that make the 4.5 hour trip (one way) worth it. Early winter is the best as the summer mosquitoes will eat you alive, at least until you get underground.
No matter where a caver steps in this area of Ontario they will be on the verge of discovering something new, every time I have been here new leads have been discovered and explored. The Marmora area of Ontario is sure to reward any caver that puts in some time looking around, above ground or under ground.
Enjoy the pics, my contact info and Caves of Ontario website link are at the bottom of the page.
