Lake Greenhow: A Forgotten Relic of the Ice Age

Yesterday’s post led me to glaciers, glacial lakes, and the like. At Botton Head, my imagination ran riot.

Difficult as it is to picture now, 10,000 years ago, a glacier covered the Tees Valley before me. The ice sheet, it is well-known, never quite managed to smother the Nor ...

Newtondale: A Gorge Too Big for Its Stream

North Dale sits at the top end of Newtondale, a gorge that stretches all the way to Pickering. Newtondale is an oddity, or so everyone says, because the little Pickering Beck, which now trickles through it, could never have gouged out such a deep, narrow valley. At its tightest points, the valley is only 500 met ...

The Chikanishing Trail, Killarney Provincial Park Ontario Canada was a rough, rugged trail over rocky terrain and the odd rickety, weathered wooden bridge or boardwalk. The fall foliage was stunning especially with the pink granite. Click link to view for #FreeShipping North America on #wallart

Pointillist dot patterns form an abstract shape, creating an intricate gnarled texture that seems to mimic a biological or geological form. The use of black dots on a white background highlights the complexity and depth of the design.

We have these amazing karst canyons all over the island & on several surrounding gulf islands. Large karst networks of caves & canyons are found in Cowichan Valley, Comox Valley & all through the less populated North Island. Karst sites on Quadra Island & some islands in the Discovery Islands archipelago are being researched. Haida Gwaii has big karst formations network.

I find #geological #karst formations very fascinating. I enjoy exploring them when there's an opportunity to do so. I've found ancient old growth tree crystals in some of the karst formation forests here - they're magical, magnificent & hard to find if you're not looking hard in the right areas.

Beautiful #textures on a #sandstone & #shale #bedrock cliff.

October 2023.
I love nifty #rocks. These are some I found in #Sooke while beachcombing with my Mom.

Not all planets are like ours. I don't just mean the water and life, I also mean the surface process. You look at a high-resolution #geological of #Mars (like this one by Fawdon et al.), and you see stories you won't see on modern #Earth.
For one, it's very old (>2 Billion years). There are also many impact craters, but there is also fractures indicating a complex stress field, fossilized fluvial channel... that is a frozen system vs. the extremely dynamic ones we have here now.

Interesting #bedrock #geological formations can be found on many beaches on the Eastcoast of Vancouver Island & surrounding Gulf Islands. A prehistoric mix of coal, shale & sandstone.
