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.
“NORTH GREYROCK MOUNTAIN FROM THE WEST”
In reviewing this after its publication, I apologize for using this poor photo. But I will keep it active because some of you have already worked on assembling the Jigidi and getting the coordinates.

The photo provides a view from the west of North Greyrock Mountain and its lower neighbors to its south. North Greyrock shows as the small grey-colored point near the left end of the photograph. Although it looks lower, it is tucked farther away from the others and is actually the highest of the peaks shown. It’s a fun scramble to reach the summit, and below the highest point, on the east side of North Greyrock, is geocache GC2KTA1 (Profiles of Greyrock Mountain–Northern View). That cache has been found seven times since it was published in 2010, and is a fun one to go after.
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 on North Greyrock Mountain!
Dogs are allowed on the Hewlett Gulch trail system and if under voice control do not need to be leashed.
