Here is a picture of the girls on Valentine's day sitting on an ice jam on the river.
And here is the same spot two weeks later after some warm weather and rain!
The river is usually just a trickle over these rocks, actually you can't really see most of the rocks.
These are the same rock that are in the blog title for comparison!
Here is an almost perfectly rectangular piece of ice that washed up on the shore of the river. It shows just how thick the ice was at one point.
