Mind if I jump in with a question?
Spearfish Creek is well known for its natural beauty and great trout fishing. It is also known for a unique phenomenon that occasionally occurs in the winter months. What is it??

No, it doesn't change direction.
This unique phenomenon only occurs when it is below freezing for extended periods of time. |

Spearfish Creek runs year round. This is even true in the dead of winter because of the speed at which the creek flows. This speed prevents ice from forming except along the bottom of the creek bed where friction and turbulence allow the water to slow down long enough to freeze. This results in the unusual phenomenon of the creek freezing from the bottom up rather than the more usual top-to-bottom of slower streams. Since the creek continues to flow atop this ice, the water level of the creek gradually rises as more ice accumulates on the bottom, in some cases causing flooding on the north side of town where the channel is not so deep.

Hmm... that's pretty interesting. Is Spearfish Creek the only one like this? I am pretty sure that Rapid Creek flows year round too. As do many creeks and streams in this region. I wonder why Spearfish Creek is the only one like this??? |
