|Two main reasons for the hike. I wanted to find Tonto Triangulation Station atop Mt Peeley, and I wanted to locate Maricopa/Yavapai County Boundary Monument #31.
Boundary Monument #31 is in the shape of a frustum.
Now, ……… who can resist finding a frustum ??
Well, I found the Tonto benchmark (1924) atop Mt Peeley. (It would be hard to miss).
The surveyors didn’t place any Reference Marks, so Tonto benchmark was the only disk to look for.
A bit of trivia. The county line between Gila County and Maricopa County goes right thru Tonto benchmark, east and west. So .…… Jump north or south over the benchmark & you’ll change counties.
After many photos and marveling at how prolific claret cup cactus grow atop Mt Peeley, I descended down the very vertical west edge. It was the shortest way to the frustum and turned out to be an easy climb down.
I then hiked along the burnt-out little ridgeline to the west. In the distance, I saw many burnt tree skeletons sticking up on the ridgeline, all twisted and foreboding. Then I noticed something very vertical, and very straight. Since nature doesn’t do “straight” very well, I knew I had located Maricopa/Yavapai County Boundary Monument #31.
This is the last (and furthest east) of a total of 31 boundary monuments set in place in 1924, designating the border between the 2 counties. The markers were set aprox 5 miles apart.
All 31 boundary monuments are in the shape of a frustum. Frustums look like 3 sided pyramids with the pyramid pointy top removed. These boundary markers contain bronze plates - one on each of the three sides, designating Maricopa on one, Yavapai on another, with the third displaying the course and distance (in ‘feet’, of all things) to the next numbered frustum to the east and to the west.
This #31 frustum however, is an exception. Since it’s the furthest east frustum, it’s bronze plate only has info to the next frustum to the west, and also, it has no course to that next westerly marker (#30). Instead the plate says ”Lat. 34 00 00 N.” since both #30 and #31 markers are on the same latitude.
So, just hike west on that latitude for 29,851.4 Feet to get to Monument #30, and see another frustum.
Surveyors used two different size frustums for the 31 border monuments between the 2 counties. 25 small ones and 6 large ones.
This #31 is the larger size, with a base-width of 2 ft 6 inches and a height of 1 ft 8 inches. It has an 8 ft galvanized pipe, 2 1/2 inchs in diameter in the center of the frustum. The pipe is driven into the ground about 3 ft for stability. The smaller frustums are about 50% smaller, including a smaller diameter pipe.
Thru a bit of research & study, I found some interesting info about the actual ‘placement’ of this boundary monument #31. (Too long & boring for a trip-log however, so I’ll spare everyone).
From boundary monument #31 on the ridgeline, I hiked north, down and thru a sloping and densely forested area to the Mazatzal Divide Trail. It wasn’t a long distance in that steep forested area, but I went very slowly, looking in all directions for signs of anything out of the ordinary. I’m sure Search and Rescue has combed that area, but since I was there, I took a good look. I found nothing suspicious.
It was a good hike, and I documented another frustum.
You can’t beat that !!
