Abbreviation “MTU” on Sectional

I didn't have anything else to do today so I began browsing my Salt Lake City Sectional. Ran across something I don't recognize. Northeast of Carbon VOR-DME along V-208, I ran across "VOR-DME 112.7 MTU." What is this?

    Well, MTU VOR is along V208 northeast of Carbon 🙂

    What you are seeing is the VFR remnant of an IFR change-over point.. You will see it if you look at the IFR low enroute chart.

    Essentially, it’s telling you that you might not get a clear signal off PUC so, if you are navigating via VOR, tune in MTU early.

    Mark, I don’t think that’s quite correct.

    What we’re seeing here is a VOR that is just off the chart. Bring up an unstitched view ofthe Denver sectional (like https://skyvector.com/?ll=39.872907885143796,-110.35018998679789&chart=18&zoom=5&fpl=%20KHSD%20undefined%201K1 )

    And you will see that the MTU VOR/DME is just off the chart. So the name and frequency is provided to aid in identifying the airway (since you wouldn’t know it otherwise, it being off the chart).

    We forget about things like chart edges with all of our stitched-together, seamless charts today.

    There are numerous examples of this on other charts as well, just have to look around the edges.

    I think you are absolutely right. If the paper sectional splits there, that would indeed be the reason it is there.
