Geocache Description:

About the location:
Welcome to Newaygo State Park. This is a coveted geocaching destination in Michigan along the banks of the Muskegon River. Enjoy the scenic walk in the woods and please bring bug spray.

About the cache:
The relaxing field puzzle is sure to be a fun solve amidst the tranquil woods. You will not encounter any elevation changes. Our family had as much fun making this cache as you are sure to enjoy making the find.

There are three common scales or rules used in the lumber industry (Doyle, Scribner, and International), but the Doyle scale is the most commonly used in the midwest. All three of the scales estimate logs closely in the medium to larger size range, but the Doyle underestimates footage on the smaller logs. Because of this, it is advantageous for buyers of logs to use the Doyle scale to make up for extra log handling on small logs. Since the buyers like this scale, it is what they use and therefore, what the sellers use.

Doyle folding log rule used by most log buyers in Midwest.

All buyers had a Doyle scale on them at all times, usually in the form of a folding rule with the footage marked at each inch.

The formula for the scale is based on a tapered cylinder, milled with a 1/4″ kerf. Straight logs, with little taper and cut on a thin-kerf bandsaw will yield more lumber than the scale predicts. It usually averages out, because logs are usually not so perfect, and often have boards that are below-grade and end up in the firewood pile.

To use the scale, first measure the average diameter of the small end of the log inside the bark (in inches). Locate that row on the scale. Next, measure the length of the log (in feet). Move over on the scale to that length column. Where those two measurements intersect, you will find the board footage for that log. The process must be repeated for each log. Deductions are made for defects, like rot and curved logs.

What's the Challenge?
The challenge on this cache could be the distractions of deer, turkey, racoons, squirrels, or an occasional skunk. The cache is fairly well camouflaged. The challenge will be learning to use the "new" Doyle Log Scale and then performing a little math. Please return the stages as you found them when completing with the cache. We hope you have fun!
