Thanks for bringing this to attention. Well, yes, I do see the omissions in the map, but this is just the v1 of the map. These things can be fixed in V2 of the maps. You should always verify any section of the map that you intend to use. Use the best map available for the job. I see that there is a separate Utah map available as well at http://www.miscjunk.org/mj/mp_uttopo.html. Maybe that does not have the mistakes and will fulfill your needs. There is no reason to lose faith in these maps. Creating the 20ft contours for entire United States is a gargantuan task and some mistakes are expected. However, for the most part, these maps pretty much provide the best seamless coverage for now.
