My husband planted this box last Saturday (watch for more from us in the
near future). Here are his instructions:

The Conejo Open Space Letterbox

This letterbox is located near Thousand Oaks, off of the 101 freeway in
Ventura County. Exit the 101 freeway at Hampshire Road and turn
south. About 1/2 mile from the freeway turn right onto Triunfo Canyon
Road. Drive another 1/2 mile and take the first right turn after Triunfo
Park. Continue up and to the right until you reach a cul-de-sac. The
number of the last house on the left is 981, on the right, 982. Park your car.

A trail exits the cul-de-sac heading northward at about 340 degrees. At
the top of the first climb you will find that you are on a ridgeline. A
trail to your left at 160 degrees leads up a hill; ignore this trail.

Continue on. . . passing first a trail, then a fire road to your
right. After a short distance and a couple of climbs, you should be able
to look to your right and see right up the 23 freeway where it joins the
101 freeway. About the time you first see the junction, it will be at true
north, 0 degrees.

The trail passes over rocky outcroppings--or maybe very old concrete--and
starts to head downward. At this time the 23-101 junction will be about 5
degrees; the junction will pass out of sight as you head downhill.

A fairly steep, rough, rocky descent ensues. When the trail levels off, a
smaller trail leads off to the right at 290 degrees; follow this trail.

As you follow this smaller trail, look to the left toward the near hills
and you will see two electrical towers. When the left tower is at 225
degrees, and the right tower at 240 degrees, leave the trail on a bearing
of 200 degrees toward a lone yucca bush about 36 steps away.

From the yucca proceed 4 steps at 160 degrees. That for which you quest
is located beneath a small cairn of rocks.


Notes:
1. All bearings given are from true north, that is, declination
applied. The local declination is 14 degrees east.

2. The hike should take about 2 hours round-trip at an easy pace.

3. The technical intensity of the hike is moderate, includes a good deal
of rise and fall and the trail is quite rocky.

4. Watch out for ticks and rattlesnakes.
