The Great Salt Lake Base and Meridian Monument and Plaque,  The stone was placed on August 3, 1847 when the original survey of “Great Salt Lake City” began.
The city streets were all surveyed and numbered from this point.

Fixed by Orson Pratt assisted by Henry G. Sherwood, August 3, 1847, when beginning the original survey of “Great Salt Lake City,” around the “Mormon” Temple site designated by Brigham Young July 28, 1847. The city streets were named and numbered from this point. David H. Burr, first U.S. Surveyor-General of Utah, located here in August 1855, the initial point of public land surveys in Utah, and set the stone monument, still preserved in position. An astronomical station, its stone base still standing 100 ft. N. and 50 ft. W. of this corner was established by George W. Dean, U.S.C.&G. survey, September 30, 1869, to determine the true latitude and longitude; it was used to obtain correct time at this point until December 30, 1897.

This survey marker lies in the sidewalk on the southeast corner of 400 South State Street in downtown Salt Lake City, Utah.

ENGINEERING DEPARTMENT
SALT LAKE CITY

STANDARD OF MEASURE

Under this cover lies a granite survey monument. It extends approximately six feet deep and is five feet square at the base. There is a similar monument one hundred feet and another one four hundred feet to the East of here. Salt Lake City Engineering set these monuments in the year 1895. They were used as the Standard of Measure for surveying the blocks and streets as they exist today.

This is located next to the DUP Marker for the Pioneer Camping Grounds on Washington Square.

    Maple Mountain / Spanish Fork Peak

    Maple Mountain is above Mapleton and Spanish Fork, I grew up in Mapleton and hiked that mountain more times that I could count or remember.    It’s a gorgeous hike but a longer one, there’s a nice pond we call Maple Lake when you’re most of the way up and it’s a great place to stop for a while before finishing.

    The trail starts at the top of Whiting Campground, a quarter-mile after that you cross the creek to take trail 007 and can’t miss it from there.
    I’ve had the hike take 12 hours up and back many times including time to play in the lake and catch salamanders but when hurrying and when in Shape I’ve gone up in 2 hours and come back down about that quick.

    There’s plenty of wildlife and scenery and amazing views of the valley from the saddle (after the lake and before the top.)

    Growing up in Mapleton everyone I knew called it Maple Mountain, the same with those in Springville – but over in Spanish Fork I found out that most people called it Flonette.  We also called it Sierra Bonita (Beautiful Mountain) regularly.    The debate continues because the SF people insist it is Flonette and other insist Maple Mtn.    Local landmarks, schools, businesses and such are named for both Maple Mountain and Flonette so trying to use that as “proof” is futile and trying to look to real or official maps doesn’t work because all I’ve seen just identify the peak as Spanish Fork Peak but do not name the mountain.  I’ve also heard that in the 50’s and 60’s it was mostly called Front Mountain.

    Several of my favorite things, a state corner (Utah/Idaho/Wyoming), a benchmark, and a coordinate confluence (a couple miles east, where the corner was “supposed” to be.

     

    It was a bumpy Jeep ride to the corner, and a gorgeous day out there.  It was really easy to find the way from the Highway in Wyoming.
