There was one time when I finally had a chance to go to the Elk Island National Park, east of Edmonton, Alberta, where they had quicksand (actually quickclay) springs (soapholes). But, as luck would have it, the Hayburger Trail that led to the area was closed due to the aftermath of a forest fire (I think in the previous year), with burnt trees that could fall down on unsuspecting hikers. So, they got a court order to make it a violation to enter that area, with legal consequences.

But, recent torrential rains before I got there had flooded everything anyways, making my hikes around other potential areas turn up meadows surrounding ponds under 1 to 2 feet of water.
