Let A and B be reflections with respect to the line L which is the perpendicular bisector of the line segment joining them. The cache is located at C which is the reflection of D with respect to L. See the diagram above (not to scale).
There are several ways to solve this puzzle. In your log, it would be interesting to encrypt a general description of your method but do not include any numerical results or any websites consulted.
Different methods may result in slightly different results. To accommodate variations in the coordinate checker, a tolerance in the lat/lon solution correct within 10 meters is allowed and will also provide you a hint on the hide. Enter your solution in the form N 44 aa.aaa W 93 bb.bbb.
You can validate your puzzle solution with certitude.
Note that points A and B as given in the table below are simply the given coordinates for #26 and #24 resp. in this series. Especially observe that it is necessary to enter the wilderness at the given trailhead. Expect a hike. This is not a P & G.
