Spring Slope Failure Along the Humber

This was a fun Spring walk with the wonder dog. They just cleaned out the fish ladder, and expect the fishies to start jumping this week. I can't wait! Just up the river is something 'anti-fish', which is a silty slope failure. You can see they put up some rock 30 years ago, but it's probably become undermined. You can always tell a slope is in trouble by looking at the trees. If they are tilted, watch out!

This slope has our infamous Queenston Shale halfway up, overlain by some beautiful cross-stratified sand. Makes for a deadly combination.

This year some fences are in for a surprise.
