BOU AVENUE
Cedar Butte

Hoping to find someplace with better weather on 2 January 2026, Zosia Zgolak and I ventured into Idaho’s Snake River Plain to hike possibly one or more of the many volcanic buttes that are scattered throughout the area.  Cedar Butte immediately attracted my attention because it is located near Big Southern Butte which I hiked in 2015.  Essentially a volcanic crater, Cedar Butte can easily be ascended via a dirt road which basically climbs up and circles the crater's rim.  This trip should have been a slam dunk for us, but as it turned out, the weather conditions would prove to make things more challenging.

From I-15, take Exit 93 in Blackfoot and head westward on US Highway 26.  Drive 43.7 kilometres and turn left onto the access road to Atomic City.  Drive 2.3 kilometres and turn left onto Taber Road (signed "2650W"; 2WD gravel).  Drive south for 2.2 kilometres and turn right onto Cedar Butte Road (still 2WD gravel).  Drive 6.4 kilometres and carefully cross railroad tracks.  Continue for another 800 metres and turn left onto a rougher dirt road.  Either park here or drive as far as comfortable (high-clearance vehicle strongly recommended from this point on).

From where we parked, Zosia and I continued along the dirt road on foot, and the fresh dusting of snow did not hinder our progress.  About 850 metres into our hike, we veered right at a split and began climbing gradually uphill through a forest of medium-sized juniper trees.  We eventually reached another split in the road at the supposed breach in Cedar Butte's crater rim.  We kept straight (right) here, and after two switchbacks, we gained the crest of the western rim.  Despite the constant presence of a bone-chilling wind, the tops of Cedar Butte were shrouded in mist as we climbed higher and would remain so for the rest of our trip.  We made a short detour to tag the western high point before circling around the south rim.  Where the road drops off the rim, we left it to climb directly up the crest of the eastern rim.  Some surprising rock outcrops near the top provided a measure of fun as we scrambled onto the true high point.  I imagine that the views of Snake River Plain and Big Southern Butte from the high point would be awesome in clearer weather, but the persistent mist on this day simply would not budge.

With no reason to linger, Zosia and I dropped off the true high point and immediately picked up the continuation of the rim road.  We then descended northward down the steep road and eventually closed our loop at the aforementioned breach.  At this point in the day, temperatures had warmed up, and most of the fresh snow on the ground had melted.  The unpredicted result was that the dirt road had turned into a muddy quagmire making travel difficult.  Even going off-trail to the sides was not much better since the soil there was the same as the road.  What should have been an easy hike back to our car turned into a messy and aggravating slog.  Even before reaching our car, I was already worried about the condition of the access road for our drive out.  As it turned out, the access road with its hardened surface was not as adversely affected by the wet conditions, and we thankfully had no issues driving out of the area.  On our way out, we briefly considered tagging another nearby butte which would have been a much shorter trip, but a few muddy steps right at the beginning convinced us to immediately abandon that foolish idea and just call it a day.
Blind ascent? Zosia hikes a dirt road leading to Cedar Butte which is hidden in the mist ahead.
At least not yet... The fresh dusting of snow on the dirt road does not hinder Zosia's progress.
Useful for shelter from a bone-chilling wind. Zosia passes through a stretch of medium-sized juniper trees.
Perfect for a loop!

At this split in the road, the right-hand branch leads to the western rim of Cedar Butte while the left-hand branch leads to the eastern rim.

Something interesting to look at besides the fog! Zosia passes some hoodoo-like formations on her way up the western rim.
Ascending into the clouds? Zosia gains the crest of the western rim.
Kinda feels like a summit! Zosia stands on the high point of Cedar Butte's western rim (S1; 1772 metres).
Still some climbing left through the fog! After circling around the south end of the rim, Zosia abandons the road here to avoid some unnecessary elevation loss.
How is it possible to be foggy and windy at the same time? Near the top, some rock outcrops begin to appear through the mist.
Hard to keep your balance on the high point  in this wind! Zosia stands atop the true high point of Cedar Butte (1774 metres) on its eastern rim.
Looper?

Dropping down the north end of the eastern rim, Zosia approaches the split (far left) to close the loop around the crater.

Yeesh, don't hike here when it's wet! With most of the fresh snow melted, the dirt road has turned into a muddy track that is very challenging to hike.
I strongly recommend picking a dry and clear day for this hike! Total Distance:  7.9 kilometres
Round-Trip Time:  2 hours 47 minutes
Cumulative Elevation Gain:  255 metres
