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.

Jeff and I made a recent reconnaissance in the Wasteland Waterway Cave system as we suspected that with the filling of the Blue Barrel sink, the cave passages had been blocked and so the deeper reaches of the cave system would now be sealed forever. But nature is more persistent than that and the sink had cleared itself out from beneath. On the surface there is a slight indent, but below the tunnel is perfectly clear.

see the video of Cave exploration in Canada – Wasteland Waterway here.

I suppose this now brings to light the question as to when we are going to push the tunnel to its very furthest endpoint. We strongly suspect that beyond the ‘gulch’ and the aerofoil the tunnels get bigger again. You ask what is stopping us? It’s a long cold crawl and a tight squeeze at the end of that which makes me somewhat leery.

sushi 101, originally uploaded by Mic2006.

Jeff has spent several years in Japan and is what you might conservatively call a foodie – so who better to teach us about Sushi. I personally have long favoured a place called Hockey Sushi in Guelph, first visited with Maggie her boss and his family about a year ago, but Jeff suggested that we needed to try Kisara, a small restaurant on the corner of Wellington and Gordon. Admittedly we had tried to visit several times before, but the restaurant has been open intermittently. I remember this spot was once occupied by an establishment called The Red Papaya, but there were some less than stellar goings on and the restaurant closed.

See the video on sushi 101 (Guelph) – a lesson in sushi here.

Dragonfly at Feldspar Mine, originally uploaded by Mic2006.

This past week I was looking at an old feldspar mine near the former MacDonald Mine (Bancroft). It would appear that the whole area is pitted with abandoned diggings through the forest and the mineral varieties range from amazonite through to Ellsworthite and uranite, a deeply shadowed quartz (smoky) being indicative of the radioactivity that is inherent in┬áseveral of the local mineral species. In fact in the 1950’s the Bancroft area was a major location for the mining of radioactives.┬áThis namelss mine that I visited in the bush was especially well endowed with the typical feldspar minerals.

As soon as I can get my Camtasia video editing software going you will be able to click here to see a short video on the trip.

Anyway this particular mine was along a barely distinguishable track that was lined with tailings which made great rockhounding possibilities. A word of caution, without even realizing it both Jeff and I cut our hands to pieces on glass sharp shards of quartz. Unlike feldspar which has a tendency to break cleanly and smoothly along natural cleavage plains, amorphous crystalline quartz breaks in a random, haphazard way with concoidal fractures – exactly like you would see in glass. You might recall that the Aztecs used to cut the chests of their sacrificial victims open with obsidian blades, this quartz is much the same.

Though bug season is now mostly behind us, they are still pretty bad in places, in particular around the stagnant water of the place that we visited. Perched on a rock in front of me was this giant dragonfly – I’ve never seen one quite as large as this. From end to end the dragonfly was probably about 4 inches in length and it sat dead still as I photographed it. You can see the circle of lights from the close-up function of my camera – reflected in its eyes. The best thing about dragon flies is that they eat blackflies.

Hopefully the dragon flies do their thing over this week as the Rockhound Gemboree 2013 is this coming weekend and those mineral gathering trips are always better when the bugs are fewer.

In the Fall 1998 edition of the Canadian Caver, Brad Wilson relates an interesting experience that he had while exploring a remote cave in the Canadian Shield. He says that he could see a small room beyond a horribly tight squeeze so instead of going face forwards like he would normally do, he went feet first and after a little struggling he suddenly slipped through into a tube – chest deep into icy water. As Brad points out, to have gone head first would likely have been the end of him.

Exploring the rock from within, as we did at Twin Trickles Cave was certainly an amazing experience. The marble and calcite was incredibly sculpted and at the bottom of the shaft pictured above, there was a room that was bowl-like, and entirely striped black and white by the surrounding rock. When I mention a cave in the same sentence that I mention Bancroft, I do not for an instant suggest that it is a site for rock and mineral collecting. Caves are natural wonders that have been thousands of years in the making. They should be left exactly as they are found.

Check out this video documentary of exploring rock and minerals from within (Bancroft) here.

Twin Trickles Cave is some short distance into the forest and on the day that we visited, it was horribly inundated with ferocious black flies – food for the bats that reside within. although Twin Trickles is not a large cave, the rooms are sizeable for Ontario and there is a long tubular tunnel that seems not to have been followed either by ourselves or Brad’s group in 1987 – obviously it is no easy task and it dips down toward the water table. There are plenty of unprobed leads in the area of Twin Trickles so there will be more trips up in that direction this coming summer.

Embryo Cave, originally uploaded by Mic2006.

JC and I spent the weekend at one of our favorite northerly destinations exploring both Embryo and Twin Trickles caves. Both these caves are seldom visited and if it were not for the initial visit by Marcus and Brad they likely would be entirely forgotten by now.

Both Embryo Cave and Twin Trickles are marble caves at the edge of the Canadian Shield (near Toronto Canada), but they are very different in character.

Much as you might imagine, Embryo Cave is a cave that is smooth inside, easily traversed, the long borehole crawl being in soft silt, while Twin trickles is a cave in which you shred your knees, cave suit and anything else on or around you. The rock in Twin Trickles is sharp and jagged, the cave dips quickly downward through jagged portals and though the marble is beautifully banded there is more a feeling of intimidation in this cavity, it varies between tight and spacious, dry and soaking wet, jagged and more jagged, with lots and lots of black flies – see video on Embryo Cave here.

IMGP1872, originally uploaded by Mic2006.

JC and I have a lead on a Pre-Cambrian marble cave that we will be exploring on Thursday. Most exciting is the fact that the area is host to several known tunnels – they are small but beautiful and where there are some, there are more. Best thought in this area will be to speculate on what is buried. The surface geography will be our initial clue, we will be looking at unexplained dips in the soil, sink points and resurgences, contacts between marble and granite, and possible funnel points that have been created by glacial erosion.

Either way there will be some good pictures of the known cave (assuming that we can find it) and hopefully we can find something else in the area that presently lies waiting for us to discover it.
