Steam Devils on Lake Superior's North Shore

February 4, 2007

With the forecast highs in the negative lower teens Fahrenheit, and Lake Superior still mostly ice-free, this looked to be a great opportunity to photograph and take video of steam devils over the lake. I cannot provide a very accurate measurement of the height of the condensation funnels, but the funnels were tens of meters tall close to shore and may have reached 300 to 1000 meters much farther out over the lake. I decided to continue my trip to do some more winter photography. Note the LACK OF SNOWCOVER. Although the snow is usually not nearly as deep close to the lake, this area typically sees two-foot snow depth or better at this time of year. Just inland, up the hill, the snow depth improved to four to six inches at best.

First steam devil I was able to catch (southwest of Two Harbors). It may have been the best.

A second, narrower funnel comes into view. On video, this was the most clearly visible.

The second funnel gets wider. Funnels were typically visible for about a minute and sometimes lasted for three or more minutes.

This one is bigger but more distant (northeast of Two Harbors).

A big fat one in the distance (Silver Creek Cliff).

This one is probably several hundred meters tall and is several miles out (near Silver Creek Cliff).

With almost no snow, it's much easier for deer to find food. They are pretty fat and healthy.
