Yes Utah wrote their constitution as mandated by the federal gov so they could obtain statehood. I.e., they were forced into it.
However, the Utah Enabling Act ("UEA") passed by US Congress on July 16, 1894 appears to have promises to the state of Utah regrading the land.
The SCOTUS has ruled such acts (UEA) are substantially contracts between private parties and obligations made thereunder are serious and enforceable.
Section 3 of the UEA has been quoted previously (as part of the Utah constitution) but I'll again add it:
The bolded portion has been ignored here. That's not how the courts treats language in a contract. That language has a purpose and the courts will evaluate it in context and in the totality of the contract (or act, in this case).
One's first question may well be why would Utah need, or want, to disavow ownership of its land?
The answer is a common sense one. The UEA envisions the US gov disposing of the land, not retaining it. Therefore clear, undisputed title was necessary. It was understood that purchasers would be reluctant to buy if there was any dispute, currently or arising in the future, between Utah and the fed gov. The portion underlined above was included to solve this problem.
Next question might be why would Utah give up its land to the fed gov for them to sell?
Well, the answer is that the fed gov was supposed to share the proceeds with Utah. See section 9 of the UEA:
So it seems obvious that there was no intention that the federal gov hold the lands in perpetuity. While I saw no date mentioned to fulfill the contract, I think it highly questionable that passage of approx 120 years without doing so can be seen as reasonable. This is perhaps doubly so given the apparent lack of effort to do so on the part of the fed gov.
Here's the law:

Here a legal paper regarding it:

The above bit of research, as brief as it is was more than I ever intended and I'm sure a lot mre need be done. However, this bit suggests to me that this issue shouldn't be dismissed out of hand as kooky, as many here have done.
I think the Western states should be treated as the other states were. That's only fair.
