Cerro Encierro
El Malpais NM
"Albuquerque is a large light dome to the E-NE, with Sante Fe smaller to the north of Albuquerque, and Grants pretty bright almost due north. Only a few lights off in the distance for point sources. A few red tower lights to the northeast. To the northwest Gallup is visible, but much smaller than seen from El Moro. Milky Way very good tonight running from Cassiopia to Scorpius. Very wide - 10 degrees at Saggitarius where there is a lot of detail. Dark lane in Signus and prancing horse visible."
