Hiking with Dogs around Sonora Pass- 5/25/2025

Post by Harlen »

Lizzie and I cruised slowly up Hwy 395, stopping for three days and nights to car-camp and day-hike. We first camped at Onion Valley, and hiked to the first lakes above there. Then we went north to Rock Creek, where the road is plowed to within a half mile of Mosquito Flat, which is 10,000,' and hiked into the snow a few miles up Little Lakes Valley. And finally, we stopped on top of Sonora Pass, and hiked north up the ridge of Sonora Mountain. It was very slow going through Bishop due to the annual "Mule Days" extravaganza.  After that, we were stalled out in Lee Vining for a few hours due a fire just to the north of town, which we hope is nearly contained now (See Maverick's "Fire and Smoke Impact Report" thread.).

We were very anxious, and excited to try out our new dog partner "Sierra" on and off the trail in her namesake range.  She did wonderfully well, and that was a very happy surprise.  At one point, we thought we would need to get one of those "E-collars," to keep her from long distance wandering, aka: Running Off!

She has learned to respond promptly to a loud clap and "Sierra Come," even with ground squirrels and rabbits in her sight.  Do you hear that Aura?

We took some photos from our pair of hikes-- one with snow shoes, around Sonora Pass.  You can park and begin to hike, or ski right at the pass, and from many locations on both sides of Sonora Pass.  We saw at least 10 sets of skiers, and admired their tracks, mostly coming down from the peak just south of the pass.  Skiers such as you c9... Sam, should note that the guys we talked to said it was a pretty nice surface of "slush over solid crust;" I'm not sure if that appeals to you?  *Early morning ventures preferred.

Much of the south facing slopes and the wide open flats found on the north side of the pass are largely melted out, and we managed without snowshoes.   Our pair of dogs loved the open sage flats, and especially the snowfields! One of our goals was to find the way back into the strange tunnel I had found on the Sonora Peak climb with Frank last spring.  ( viewtopic.php?t=23564)  We thought we were going to be foiled by steep snow, but it turned out that the tunnel, which pierces the volcanic ridge, was open at each end, with the snow just melted away from the eastern entrance.

Volcanic breccia-- Pyroclastic stuff of explosive eruptions.  It is interesting for us "Southern Sierrans" to be surrounded by volcanic rock.

View west from the tunnel, you can see a small curve of Hwy. 108 circled in red.

Sierra is a super-affectionate dog, and just what we needed after losing our dog Bearzy last summer.

The hike up there was through a early flowering garden of Whitebark Pines and sagebrush scrub.  The Mule Ears were just poking up through last years leaves, and the Lupines were still in leaves only.  We found some rare Alpine Paintbrush, Castilleja nana (if that's still it's name), and the lilac-colored flower Frank and I had wondered about, and never named.  It was there again in profusion, it looks a bit like a Polemonium species, kin to the Sky Pilot, but I am guessing.  The next most common flower up there right now is the Spiny Phlox.

We learned that Sierra will not require tennis balls in the mountains. :thumbsup:

The pure snow on the north side of the valley appealed to us, so we made a final hike on snowshoes into the shady forest; the dogs were ecstatic!

We had a lot of fun searching out some of the last, best snowy spots.  At both Onion Valley and Rock Creek, you can be in the snow after just a mile or so, and at Sonora pass (And the same is surely true for Tioga Pass), you can walk from your car door right on to it.  Have fun out there.

A fun snow trip. And interesting to find the tunnel that you had discovered on a previous trip. Your new pup is sweet-looking. Dogs love snow. Thanks for sharing your trip.

Shise! I see a couple duplicate photos slipped in. Can they be removed maverick? (2 from the tunnel)

Hi Ian -
What a nice trip! I love the Sonora Pass area; the first couple times I went camping with friends (in high school) were at various places in the Stanislaus watershed.
Your new dog Sierra is a real beauty; with those long legs she would be impossible to catch up, so good thing you've got a strong recall response from her.
Despite my botanical ignorance (and with the aid of the Calflora website), I'm guessing your "unidentified flower" might be Phoenicaulis cheiranthoides (Dagger Pod)
https://www.calflora.org/app/taxon?crn=6448
... a good confirmation would be looking at the INaturalist website- the Sonora Pass area has many confirmed observations of this species.

Anyway thanks for posting, I'm sorry I didn't see this earlier.
Mike

I am so happy to see that Sierra is cooperating and staying close by! I gave up on Jasmine Rose after 5 years of training. The dog has Marmot delirium syndrome and a generally insane prey drive. How is she doing otherwise? I mean the separation anxiety?
Lovely trip! Can’t wait to see more!!
