Posts Tagged ‘Bruce Peninsula’

This is a shaft at the back of a well known sea cave on the Bruce Peninsula. It might appear that I am desperately fighting a giant serpent that is in the process of swallowing me. Well gravity is on it’s side and I slid quite easily down its throat.

This particular weekend was a very successful one for caving in that area. JC and I located a swarm of deep rock shafts and we are returning quite shortly to conduct further investigation. We had been pointed in this direction by the exploits of cavers from decades past. The majority of our cave discoveries had been from building upon the investigations of others.

See my video on some caves beneath the Bruce Peninsula here – video on caving beneath the Bruce Peninsula.

It is here at the very tip of the Niagara Escarpment that Ontario caving is at its very best. And the discoveries of what lies beneath is just beginning. There are countless kilometers of bush and limestone alvars that remain to be explored.

As it was a beautiful warm day in early April, JC and I headed up to conduct some further exploration on the Bruce Peninsula. Our intent was to try and locate a stream that we had heard of; apparently this stream drains a sizable plateau and normally flows with at least 10 cubic feet of water a second. Being a plumber JC estimated that a 1 foot high by 2 foot wide pheratic tube might flow with about 4 cubic feet a second, but 10 cubic feet might possibly be human sized, also considering that we have had an especially dry winter so who says that the tunnel will be full of water. An ambitious caver might slither up that worm hole and find bigger passages on beyond that entry portal.

Well we never found the stream as we were sidetracked by a visit to a well known local sea cave (see the picture above) and then as we were heading up toward the stream that we had heard of we we were again way-laid by what looked like depressions in the forest. Well one thing led to another and those depressions morphed into incredible solution shafts – several of them grouped together and deep, deep, deep (but that’s another post). We spent the rest of the afternoon assessing the local geography and seeking to understand the situation with all those pits. We are in no doubt as to the possibility of a cave system beneath – the surface features kind of remind me of the sinks and their dispositions around Museum and Leopard Frog Cave, its just that they appear to be totally relic from the ice age and subject to some heavy water pressure beneath a glacier (Museum and Leopard Frog are still obviously recharged with surface running water).

More to follow on this exciting new cave possibility (including video). It makes C-Hurst look a lot less impressive for the depth and volume that these new solution shafts encompass.

Entrance – Rover’s Cave, originally uploaded by Mic2006.

Earlier this year JC and I visited an obscure Ontario Cave. Though it is in Ontario – many hundreds of kilometers from the Ocean this is what is known as a sea cave.

Rover’s Cave is not so easily accessible, it is situated in a cliff face along the edge of Georgian Bay, screened by trees and only found after some pretty heavy hacking through the bush.

As in any search for caves, its seldom easy – if it were everyone would know about the cave. One point though, it would have been nice to have the right co-ordinates. JC kept counting down as we approached – 140M, 80M, 40M, We are there, but we weren’t. It took about an hour more and it was only by speculation and comparison of numerous likely points that we eventually found it.

Rover’s cave has over 100M of passage and in that respect it is quite outstanding for a local sea cave. From below the entrance looks like a slot on a ledge, but from within looking out there is this beautiful elliptical entrance within which you can sit and gaze out at the scenery.
