Member Star Parties


For many amateur astronomers, participating in club star parties is the best part of belonging to a club. These friendly nocturnal gatherings give observers a chance to talk about all things astronomical, look through many types of scopes and show off a few of their favorite sights. EVAC offers at least two star parties each month (weather permitting, of course.)

EVAC Member Star Parties


EVAC is not currently supporting star parties at the Picket Post Trailhead.  Some members gather during the weekend before and on the weekend of the New Moon.  Due to Forest Service rules, a Ranger is present from spring to fall.  Gates are locked at sunset when the Ranger is present.  For this reason members are encouraged to use open areas off the road before Picket Post if the gates are locked.

  3. Just past that you will see a yellow 'Truck Crossing' sign... and just past the sign is FR 231.

  4. The road is now easier to spot than in the past, as there is now a familiar brown sign indicating the trailhead.

  5. You'll know it's the right road because there is a small windmill visible just after you make the right turn.

  6. Follow the well-graded road about half a mile to where it dead-ends into another road.

  7. Another brown sign indicates that you should make a left turn (staying on FR 231) to get to the trailhead.

  8. This section of the road is asphalt.

  9. Follow the narrow road about a half mile until it ends at the trailhead.

  10. When you reach the trailhead, bear to the right and circle around until you see the larger, flat area.
