Air Quality in Joshua Tree National Park
We in the Morongo Basin are so closely connected with Joshua Tree National Park that its air quality issues are ours. Most of us have seen the smog around San Gorgonio Pass where the I-10 and Highway 62 intersect. Read more about air quality in the Park on the JTNP Air Quality page.
The National Parks Conservation Association has produced a fact sheet about haze and smog in JTNP.
