what is the frost line in Grand Junction ?
Mesa County Colorado
Sorry for the delay in responding to you, I was trying to research this, and not coming up with very satisfactory answers. It varies from year to year, and a pretty good estimate seems to be zero to twenty inches! Most of the maps give 15 as an average for this part of Colorado. If you are needing this information in regards to building/construction, you might wish to contact NRCS.
