Tex Creek Zone Context
Eastern Idaho — Wildlife Management Area
The Tex Creek elk zone consists of Units 66 and 69. A zone name does not make every parcel subject to the same rules as Tex Creek Wildlife Management Area. Match the intended route to its actual land manager, unit boundary, and current hunt restrictions.
Consider Idaho Falls when arranging supplies. If visiting the WMA, check its current seasonal closures and authorized travel routes separately from your elk season dates.
