Get a copy of The Guide To National Parks Of the Southwest,, Published by Western National Parks Association and it will provide an excellent review of the 4 corners region. We have made trips through there in each of the last two years about 2 months each time and plan to go back again this spring. We have yet to see the exact monument though we have passed near by several times.
Highlites of a tour would be, Zion, Bryce, Capital reef, Canyon lands, Arches, Mesa Verd, El malpis, Petrified forest, Grand Canyon.
Not a summer trip, watch out for winds
