Greyrock Mountain (elevation 7,613 feet) in Larimer County has a highly distinctive profile from Interstate 25 and other eastern vantages. Its steep southern aspect shows dramatically in silhouette as seen even as far east as I 25. Many admirers of this Ranked Peak do not realize that the mountain’s (as well as those of its satellite peaks) lines from other directions are also remarkable and highly distinctive. Views of this mountain from various directions are breathtaking, and each provides a special profile dimension of Greyrock and its numerous ranked peak neighbors.
In June 2010 I published the first in a series of caches about these distinctive directional profiles: "Profiles of Greyrock Mountain--Northeastern View" (GC26C63). The series grew to include 10 caches plus a mystery cache that requires visits to eight of these original caches. The profile caches became popular with serious back-country geocachers and those original caches, plus others I've created in the Greyrock Mountain area since that first one, now comprise more than 30 caches.
"AIGUILLE DU GREYROCK FROM THE WEST"

The photo provides a view from the west of the Aiguille du Greyrock, the sharp point off the western end of the large, impressive rock formation. This is the "needle of Greyrock", shown on the USGS 7.5-minute topo map as Point 7456. It's a Ranked Peak that is infrequently climbed by peak baggers, in part because of the moderately long hike to reach its base and in part because of its imposing terrain. There is a geocache near the Aiguille's summit, GC2KRKN, that has been logged nine times since it was placed and published in 2010.
After you place the final piece of the Jigidi puzzle a "completion" message will provide the coordinates of this cache as well as a hint for finding it. The signal bounce in the cache vicinity can be significant. Hence, the completion message provides some detail that should allow a fairly fast find if the instructions that are presented are carefully followed. The hike is along the Hewlett Gulch Trail; reaching it and returning to parking involves about an 8-mile round trip having a cumulative elevation gain of over 1,200 feet, all on this well-used trail. So go prepared with snack foods, plenty of water, extra clothing in the event of weather changes, etc. And before leaving on the hike let someone know your plans and planned route and destination. Enjoy the puzzle and the cache-finding experience. As a personal reward, plan to later make a climb of Greyrock Mountain or of some of its satellite peaks that are featured in the Profile series and nail other caches along the way--including the one at the top of the Aiguille!
Dogs are allowed on the Hewlett Gulch trail system and if under voice control do not need to be leashed.
