CAS observing is managed by members on a private email list. This mailing list allows them to quickly notify other list members if they are going observing that day or weekend.

• Turn LEFT onto S. Lone Tree Road and Go 0.2 miles to the intersection at J.W. Powell Blvd.
• Turn RIGHT onto E. John W. Powell Blvd. and Go 1.0 mile to Lake Mary Road.
• Turn LEFT onto Lake Mary Road and Go 8.2 miles. There is a brown sign on the right side of the road for “Marshall Lake” and “NPOI”.
• Turn LEFT shortly after the sign onto Coconino County 128.
  (The identification for CC 128 only appears after you are on the road.)
  CC 128 is a switch-back road going up the side of Anderson Mesa.
  
  … From the Lake Mary Road onto CC 128 turn, Go 1.3 miles up the switch-back.
  You will see a sign for “Marshall Lake” and “Lowell Observatory”.
• Turn RIGHT just before the sign, and head towards “Lowell Observatory”.
  Go 0.3 miles up to the observing site at the top of the mesa.

• Take I40 east from Flagstaff to US89 (exit 201, Country Club, Flagstaff Mall).
• Follow 89 north to the Wupatki National Monument (about 26.2 miles)
• Turn right (east) into WNM and go about 9.3 miles (well past the Lomaki ruins on the left and the Citadel pull-off on the right), and turn right, onto a very short road ending in the parking area. A small wooden sign on the left marks the turnoff, but is hard to see in the dark (If you drive through the cinder cones and start descending rapidly you've gone too far!).

Note that the Dony Picnic Area is in the Coconino National Forest and not the Wupatki National Monument.
