Poison Creek Creek

Expected Conditions:
Class 3C1-IL The lower technical section contains between 1 and 3 rappels.

Drive West out of Marsing on Hwy 55/95. Get off at Cemetery Rd just as the highway turns northward towards Homedale. Drive West on Cemetery Rd for 1 mile. When the road ends, turn left and drive South for 3 miles to Jump Creek Rd. Turn right and drive West for about 1.4 miles. Cross Poison Creek and the canal and follow the road SW towards the mountains. Just before the road starts up the hill there is a house and a no trespassing sign. There is a side road that bypasses the house (see blue line on included map). The side road is not suitable for passenger cars. After 1.3 miles from the turn at the canal there is a small side road coming out of a turn out on the left side of the road at the apex of a switchback. Park here (N43 29.798', W1160 57.442'). This is the lower trailhead. From here, hike up the grassy hill to the S to reach the top of the bench, then veer SW through a shallow gully (this may be worth expioring), over the rise, and then down a steep grassy descent gully to the bottom of thecahyon just above the lower technical section.

Use the upper trailhead if hiking the whole canyon (car spot) or exploring the upper forks. Continue up the main road to where a small side road crosses (N43 28.7171, W1160 58.527). Park here.

Hiking Directions:

West Fork:
From the upper trailhead, hike SE-E down the gentle hill into the canyon and then turn left to follow the (:reek. The canyon gradually narrows in. There are two pools. The first is only a couple of feet deep. lt can be bypassed with some dass 5 climbing up and over on the left. The second may be deep enough to swim. lt may not be possible to bypass this pool, though someone might try with a daring leap or a hook and aider. A handline could be useful for getting into this pool. From here the rest of this fork is not chatlenging.

East Fork:
The East Fork has not been fully explored. This contains at least one rappel. There are probably no more. The height of the rappel is estimated at 40 feet, but lt has not been measured. There may be shallow water at the base of the rappel. Above the rappel is unknown. The lower portion of this fork does not seem to hold much water.

Upper Main Canyon:
Below where the two forks meet, the canyon is wide and long. There are areas of easy walking but for much of the distance there is brush to pick through and rocks to scramble over. The easiest line is right down the creek.

Lower Technical Section:
Near the bottom of the canyon, a wide grassy side gully cuts through the rock into the canyon from the left (LDC). This is the decent route if hiking only the technical section from the lower trailhead. Past this spot the canyon walls quickly dose in. lt is possible to stay out of the water all the way to the brink of the first rappel, or beyond if using the bypass. This rappel is 20 to 25 feet down a steep cascade into a pool that is likely deep enough to swim. Unless using a lot of webbing, rocks will have to be gathered to build an anchor in the water at the top of the rappel. lt is possible to bypass this rappel by climbing onto the wide but slanted moss covered ledge on the right. From above lt appears that the ledge ends but lt is possible to climb down past what can be seen. Following the rappel and pool, the canyon descends a narrow chute and then turns left to the brink of a second rappel. This mandatory rappel is probably about 50, maybe 60, feet high, down a beautiful waterfall in a narrow chute. At the bottom of the waterfall is a large pool that is likely deep enough to swim. Immediately below that is another small waterfall. This can be rappelled or lt can be bypassed by climbing across a narrow exposed ledge on the left (LDC). Below 7this is a slab climb and then a tricky leap along the right wall to avoid a swim below. Avoid the final pool by going .over the hump on the left. From the mouth of the canyon, return to the lower trailhead by hiking over the small hill on the left and then up the 4w4 track up to the main road.
