It's a wee bit cooler today but nothing like 126,000 years ago when the #AtlanticBubble was covered in ice!
The last ice age ended 10,000 years ago but there have been glacial periods in #NovaScotia on and off for at least 500,000 years...

During periods of climatic cooling, ice sheets develop and advance, aided by the reflection of the sun's light from the white snow surface. Sea levels drop as ocean water is used to make ice. The glaciers grow, coalesce and flow all the way out to...

We love getting questions about #mining, #minerals and #geology! We were asked about the red soil and sand at #CabotsLanding Provincial Park in #CapeBreton. Here’s our answer:

Sand and soil are eroded rock. Red sand and soil, like at #CabotsLanding, eroded from rock with significant iron content. Iron oxidizes/rusts when exposed to air, so the red is rusted iron.

The sand, soil and clay at #CabotsLanding are glacial outwash - sediments deposited by glaciers as they melted at the end of the last ice age 10,000 years ago. Much of the sediment is eroded from the #CapeBreton Highlands, which used to be much bigger.
