Welcome to my Map Projections Series!
We all are familiar with coordinates as we all play this great game of geocaching, but how well do you know your map projections? Once you get the hang of solving these, you’ll be through them in a snap! This is my first attempt at a puzzle series – and I hope I’ve kept it pretty straightforward. Everything you need to solve is on this page. What’s in a name, anyway? Why, the names of some different projections of course!
In all cases 0 = 0 AND THIS ONE is NOT like ALL the others!

Ever heard of the book “How to Lie with Maps”? Well, these are just seven more common map projections of hundreds throughout the world. Each projection can be used to emphasize a different area, useage or focus. They portray all or part of the round Earth on a flat surface, which cannot be done with out some distortion. Every projection has its own set of advantages and disadvantages. There is no "best" projection. The key lies in mapmaker selecting the one best suited to the task at hand, reducing distortion of the most important features.
Mapmakers and mathematicians have devised almost limitless ways to project the image of the globe onto paper.
Orthographic
An orthographic map projection, like the stereographic projection and gnomonic projection, is a perspective (or azimuthal) projection, in which the sphere is projected onto a tangent plane or secant plane. The point of perspective for the orthographic projection is at infinite distance. It depicts a hemisphere of the globe as it appears from outer space, where the horizon is a great circle. The shapes and areas are distorted, particularly near the edges, but distances are preserved along parallels.
The orthographic projection has been known since antiquity, with its cartographic uses being well documented. Hipparchus used the projection in the 2nd century B.C. to determine the places of star-rise and star-set. In about 14 B.C., Roman engineer Marcus Vitruvius Pollio used the projection to construct sundials and to compute sun positions.
Vitruvius also seems to have devised the term orthographic (from the Greek orthos (= “straight”) and graphe (= “drawing”) for the projection. However, the name analemma, which also meant a sundial showing latitude and longitude, was the common name until François d'Aguilon of Antwerp promoted its present name in 1613.
The earliest surviving maps on the projection appear as woodcut drawings of terrestrial globes as early as 1509 but a highly refined map designed by Renaissance polymath Albrecht Dürer and executed by Johannes Stabius appeared in 1515.

All these placements were Winter Friendly when hiddden but one or two may not be if we get more than a foot of snow - for those caches, check the attributes; they won't be listed as winter friendly. Also, come spring some may require a little more bush stomping and might be in slightly wet areas - I'll update the attributes/comments when the snow melts and I can see the conditions.
The parking coordinates provide a good starting point to walk the entire series. Although the trail crosses the #1 highway at one point, the parking there is not safe, meaning though this cache looks like it could be a park and grab, it's probably better not to.
