Volume 2 of the ‘Rockhound’ series is now available. This particular volume focuses on the perception of value in mineral resources and the shifting lens through which Ontario’s mineral wealth is seen.

In Rockhound: Opening the Treasure Chest we visit such old collecting classics as the Saranac Zircon Mine, Bear Lake, Grace Lake, Bessemer Mine and Kuehl Lake. The mineral focus is on apatite, rare earths, tremolite, diopside and the more exotic treasures that are displayed at the Bancroft Gemboree. For any rockhound, mineral collector or crystal enthusiast this is without a doubt an invaluable accompaniment to a summer of collecting. Within ‘Rockhound’ you’ll learn how and where to collect. Over 80 mineral locations are detailed along with directions and specifics on the minerals found there.

If you are interested in purchasing a copy or Rockhound: Opening the Treasure Chest visit the Lulu purchasing site here.

IMGP1430Well as you’ve probably gathered by the above picture, I’ve just discovered some pretty incredible mineral specimens – a pocket of gem quality tremolite at the contact between quartz and calcite veins. Tremolite evolves to actinolite under the right conditions, and sometimes changes to diopside. Anyway, the finer points of the discovery are detailed on my youtube site (caver461) and within the video details are provided for the purchase of my latest book on minerals – ‘Rockhound: An Experience of the North’. In the book I detail how to find gemstones and something of the experience of finding rocks and minerals in the north.

To see purchase details or for a preview, just type the book name into Google and click on the link, it will take you directly to the print company (Lulu), or click this link here for immediate access to the book on Lulu.

This past weekend Jeff and I visited a spot in the forest where we had found a tunnel this past summer. We had been trying to dig into the tunnel but the bugs were terrible. Now that the ground is heavily laden with snow there is no such problem – now its the cold. Anyway, after about 4 hours of digging and levering frozen boulders we managed to create a hole large enough to look well into our suspected cave and what we saw within was an elliptical shaped tunnel that was plugged by boulders. A small waterfall dropped from the roof of the tunnel and beyond, a chamber in marble.

See video for Snowgof – breathing tunnel here.

We are yet to access the chamber, but with great difficulty Jeff photographed a small segment of the chamber. In his picture you can see a wall of pure white marble and you can hear the water falling within.

Near the entrance the roof is encrusted with frost thus indicating airflow from deeper in the earth. In fact it was the smear of frost on the wall outside the cave that first got us digging there in earnest. Based on its proximity to the edge of a steep slope and no apparent resurgence at its bottom I am left to conclude that the water flowing into the cave must be dropping down deep quite quickly. I suspect that it goes down a shaft such as you see in Twin Trickles Cave.

Spring will reveal what lies beyond.

This past weekend Rob, Jeff and I visited Embryo Cave with the intention of digging out something of the earth plug at the lower end of the cave’s main stream passage.

see video of Cave Exploration in Canada (video) here

lying pressed between the rock and the dirt it was an experience from which I was unable to shake the feeling that it was as though we were returning to mother earth. We dug for some time in the earth as we suspected that in breaching an earthen crest up ahead we would possibly break into tunnel that led onwards and downwards. There appears to be a lower water filled level in this cave. The flowing stream bubbles up in sand part way along the main trunk passage and it sinks again just short of the earthen plug.

Sadly we tired before we got through the dirt, but it was close and next time we visit we will certainly complete the job.

For cave exploring in Ontario this one is possibly one of the more exciting possibilities. This past weekend Jeff and I explored the tunnels for some short distance, but we were turned back by the conditions which were less than favourable – namely the cold, the prospect of a storm on the surface and my knee pads which kept sagging down and so my knees were torn to shreds.

nevertheless, for Adventure in Ontario I am still optimistic of eventually reaching the end. Thus far several pushes have not revealed the sump-point. On one trip we reached a spot called the aero-foil and past that a squeeze then bigger tunnels beyond.

I am thinking that the cave goes deep and the many sinkholes in the area must meet up with these tunnels somewhere beyond where we have crawled.

We hiked through a jumbled terrain of massive slabs fallen from the cliff face and rounded boulders that have been washed by epic wind-spawned storms.

As entrances go these sea caves far surpass others that I’ve seen, though admittedly there are few sea caves to rival Rover’s some distance further along the shore.

In the picture above Jeff and I have been hiking and reached the end of dry land. Further progress would have to be through Georgian Bay’s icy water. What I found most intriguing about Cave Point was its sea caves part way up the cliffs. For the most part it looked like difficult climbing and I’d imagine few if any people have ever visited some of those harder to reach places.

SeeĀ video on our trip to Cave Point (Georgian Bay)

Our initial idea had been to see if we could locate low-lying bedding plane squeezes close to the water line as we are aware that not every opening in this area is a sea cave, there is huge potential for solution caves and as has already been discovered, there are nearby that are intensely decorated with speleothems.

What is adventure travel in Ontario is for cavers a regular Sunday afternoon. Rob, Jeff, Jeff and I revisited this marble cave to hopefully explore other, thus far un-visited passages.

see video on Adventure travel in Ontario – Exploring marble caves, here

At this time we have discovered several other likely cave leads in the area, in particular, a sinking stream (thanks Steve M.) with massive potential for tunnels, but unfortunately it will take some land-owner permission and then a concerted effort by a team with capabilities of heavy rock removal.

Within our already visited cave we explored out into the darker nooks that I had missed last visit. We found several going passages. This particular spot as seen above – with the wad of flowstone marks the entrance to a tube that we are yet to explore. Getting to this spot is somewhat disarming as you wade through about 18 inches of water and 2-3 feet of soupy mud. Every step causes the water around you to literally boil with escaping methane. You can feel sticks and branches down beneath the mud and in their decomposition they are releasing gas. I am wondering what effect open flame might have on the journey across the expanse that leads to this spot.

Anyway – distant as this location is from my home in Guelph, it seems to be rife with caving possibilities so the focus for our caving exploits seems to be increasingly concentrated in this area. There are many karst features in the limestone right at the edge of the shield – in part due to the rocks natural suitability and in part due to the acid water running off the shield.
