 Heizer Trail Pikes Peak or BustThis photo was taking at the posted coords of the cache. Once again, there are no clues at or near this wagon.  Spoiler AIf you see this, then you are "Close" to Spin Off...  Spoiler BIf you see this, then you are "Closer" to Spin Off...  The cache is "NOT" at the listed coords. However, there is a great "Pikes Peak or Bust" wagon near by. You must solve the puzzle, in order to log this cache. This cache was inspired from the cache, "SPIN UP", GC14H7F. That and the fact I just figured if you hiked this far, you might want to justify it by hunting for two caches. When I told Vorticity that I was going to go and seek his cache out, he suggested that I might just leave an extra cache up on the mountain. (So this cache was placed in his honor.) Happy Caching, and I hope you have a SPIN or TWO while on your caching journey... While researching Spin-Up, I found a few extra definitions of VORTICITY on the Web. I just thought you might enjoy reading a few more. A measure of the amount of "spin" (or rotation) in the atmosphere. A measure of the rotation of air in a horizontal plane. Positive (counter-clockwise or cyclonic) vorticity can be correlated with surface low development and upward vertical motion (in areas of positive vorticity advection). A measure of the spin of a fluid, usually small air parcels. Absolute vorticity is the combined vorticity due to the earth's rotation and the vorticity due to the air's circulation relative to the earth. Relative vorticity is due to the curving of the air flow and wind shear. The measure of fluid rotation. In synoptic scale meteorology the term usually means the relative vorticity about the local vertical. A vector measure of local rotation in a fluid flow, defined mathematically as the curl of the velocity vector, where is the vorticity, u the velocity, and the del operator. The vorticity component normal to a small plane element is the limit of the circulation per unit area as the area of the element approaches zero (see Stokes's theorem). The vorticity of a solid rotation is twice the angular velocity vector. A measure of the local rotation in a fluid flow. In weather analysis and forecasting, it usually refers to the vertical component of rotation (ie, rotation about a vertical axis) and is used most often in reference to synoptic scale or mesoscale weather systems. By convention, positive values indicate cyclonic rotation. A vector measure of the local rotation in a fluid flow. This can be evidenced by upper air parameter fields as well as the relative circulation observed in satellite imagery. The measurement of the rotation of a small air parcel. It has vorticity when the parcel spins as it moves along its path. Although the axis of the rotation can extend in any direction, meteorologists are primarily concerned with the rotational motion about an axis that is perpendicular to the earth's surface. If it does not spin, it is said to have zero vorticity. In the Northern Hemisphere, the vorticity is positive when the parcel has a counterclockwise, or cyclonic, rotation. Vorticity is a mathematical concept used in fluid dynamics. It can be related to the amount of "circulation" or "rotation" in a fluid. Synoptic scale vorticity is analyzed and plotted on the 500-mb chart. Vorticity is a clockwise or counterclockwise spin in the troposphere. 500-mb vorticity is also termed vertical vorticity (the spin is in relation to a vertical axis). This vorticity is caused by troughs and ridges and other embedded waves or height centers (speed and directional wind changes in relation to a vertical axis). A wind flow through a vorticity gradient will produce regions of PVA (Positive Vorticity Advection) and NVA (Negative Vorticity Advection). PVA contributes to rising air. Vorticity caused by a change in wind direction or wind speed with height is termed horizontal vorticity (the spin is in relation to a horizontal axis). Horizontal vorticity is most important in the PBL (low-levels of atmosphere). i.e. If the wind at the surface is southeast at 30 knots and the wind speed at 700 mb is west at 60 knots, there will be a large amount of speed and directional (veering) shear with height and therefore a large amount of horizontal vorticity. Streamwise vorticity is the amount of horizontal vorticity that is parallel to storm inflow. Storm inflow is the velocity of the low-level wind moving toward a thunderstorm. Helicity is the amount of streamwise vorticity that is available to be ingested by a thunderstorm. Helicity is a great chart to use to assess horizontal vorticity and the threat for rotating thunderstorms. In summary, vertical positive vorticity contributes to upper level divergence in the PVA region and thus rising air while horizontal vorticity is important to severe weather (large values of horizontal vorticity lead to large values of Helicity, which increases the likelihood of tornadoes in association with supercell thunderstorms). Both vorticity types are a clockwise or counterclockwise rotation, but one is in relation to a vertical axis and the other a horizontal axis. There are two ways to find this cache. I'm only going to point out one. I have attached a couple of pictures that will help you locate the cache, once you reach the final location of the cache, regardless which option you selected in order to break the puzzle. From the listed Rest Stop Coords (N38 53.390 W104 58.710,) you will need to go 0.33 of a mile with a "True" heading of 250 degrees. Oh and that distance is as a crow flies. Happy Caching! as with many things in Nature -- the more we know, the more puzzles reveal themselves...
**Congrats to "Mtn_Goat" for being the FTF, 8/20/07!** Additional Waypoints RS157BR - Rest StopN 38° 53.390 W 104° 58.710 This is a wonderful resting place, with a great view. From here you only have to go 0.33 of a mile, with a TRUE heading of 250 degrees, as a crow flies.
