Solid granite rock lies underneath all parts of Long Lake Park. The bedrock can be seen in some places. It often looks like pavement because thousands of years ago a great sheet of ice moved slowly over it, scraping and smoothing the surface. Gouges which show the direction of movement of the glacier can often be seen. Some giant ‘erratic boulders’ are perched on the pavement, left there by the ice when it melted. The bedrock itself was formed millions of years ago beneath a massive range of mountains that were higher than the present-day Rocky Mountains. Our mountains have gone now, eroded away to leave the granite basement which had welled up beneath them long ago. Rocks have so much to tell us!
Great introductions!
