The Yankee Springs Recreation Area houses a few interesting geological features as well as multiple campgrounds, lakes and hiking trails. Trails are relatively easy and well marked. Some contain loose sand. The hike to the edge of the Soup Bowl is relatively easy, but hiking to the bottom and back out would rank a 3+ on the difficulty scale because of steepness (although some ride mountain bikes down it). This Earthcache is located in the Yankee Springs Recreation Area. With a Michigan Parks Permit, you can park within 0.15 miles of the cache. Without the permit, the hike is significantly longer. This park is surprisingly under-utilized most of the time. There are a couple of campgrounds nearby and a significant trail system connects them all to the numerous features and lakes in the area. Many of the trails support horses and mountain bikes.
Kettle formations occur when portions of the glaciers that use to cover Michigan detach from their parent glacier. These smaller pieces of glacier grind cone or "kettle" shaped depressions into the ground as they melt. The Devil's Soup Bowl is an example of a kettle formation. Although kettle formations can be relatively common in areas that were once covered by glaciers, the Devil's Soup Bowl is somewhat unique because it is not filled with water. Most kettle formations fill with water and become lakes (often named Kettle Lake or Round Lake). This formation is dry because the grinding glacial movement broke and distorted the bedrock beneath it. It is one of two known "dry" kettle formations in Michigan. Glacial activity in this area was extremely high and has left behind numerous formations and features. The local water table is at drastically different depths across a given area because of the effect of the glacial movement distorting the bedrock in the area. While one water-well may be 80 feet deep, another nearby may be 400+ feet deep.
To get credit for the find you must do 2 things:
1. Take a picture of yourself, and either the Soup Bowl or one of the signs denoting the Soup Bowl in the background, and post them with your log. Any entries that don't post the photos will be removed.
2. Estimate the depth of the formation and e-mail me your answer. Please do NOT post it, or your entry will be removed. You must complete both steps to keep your entry from being removed.
