Triple T, I was told by some older Navajos about Juniper being used. The other two, I'll have to see if I can remember the book. It's in our local library Arizona regional section.
I can tell you this: In Northern Arizona (that's Hopi and Navajo territory and was Sinagua, Coconino, and Anasazi before that), all you're going to find here in quantity is Ponderosa pine (at elevation), Juniper, Pinyon, Sycamore, Gambel's Oak (at elevation), and some Mountain Mahogany. The Pinyon nut was a staple here in Native diets, both past and present, so we know those trees existed in great quantity. You can't go many places here without seeing ancient pottery shards laying on the ground. The Juniper was also very important and stilll is. It's used as incense (the tips of the needles.) I've seen Alligator Junipers here with a trunk girth of 3 to 4 feet, and one larger than that. Do some reading and those trees are several hundred years old. So, we know those trees existed.
In this region, around Flagstaff, bows had a great defensive purpose, as well as hunting. If you go to places like Walnut Canyon, you'll note the place was built almost fortlike. There was a huge drought here that caused a lot of migration and probably a lot of small scale wars over resources. Out where I collect pinyon sap, there are pit houses built by a canyon where water once flowed. Near there is a lone volcanic plug about 100 feet high. It was stone walls built there. Most likely, a sentry post for the canyon-side village. The primary workable wood now, as then, is Juniper for this region.
The big villages here were at Walnut Canyon, Wupatki, and out in Winslow, Homolovi. They all have websites. I suggest a visit to them all, except Homolovi is closed til who knows when. You'll never forget a visit to Walnut Canyon. I've been there several times, and I live only a few miles from it. And I notice something new every time.
