Report from May 10, 2026<\/em><\/p>\n

I\u2019ve always said I\u2019d only try Red Slate if it was a big snow year, yet there I was at 5:30 am, head down, pounding a dirt trail in sneakers and heavy pack, praying for snow to show up within 5 miles\u2026<\/strong><\/p>\n

2025\/26 has been a dry one around here and the unprecedented heat wave in March really put a dent in the California snowpack.<\/strong><\/p>\n

    Up at 4:15 am.<\/strong><\/p>\n

    Walking by 5:34 am.<\/strong><\/p>\n

    The day felt like a test.<\/strong><\/p>\n

    <\/div>\n<\/div>\n

    Tall Carl said he\u2019d made it to the top in 6.5 hours two weeks ago.<\/strong><\/p>\n

    My goal was 7 hours and I knew to hit that mark, I\u2019d have to move full speed all day and minimize breaktimes.<\/strong><\/p>\n

    I started out blazing down the trail.<\/strong><\/p>\n

    The secret to this day is that there are no real steeps until the very last 200 vertical feet.<\/strong><\/p>\n

    When I first saw Red Slate early in the day, it appeared within reach.<\/strong><\/p>\n

    An hour later, Red popped up again, clearly no closer, and I started doubting my intentions\u2026<\/strong><\/p>\n

    The first 4.4 miles of the day are on an immaculately groomed trail, allowing for long strides and quick, mindless steps.<\/strong><\/p>\n

    After 2 hours with no breaks, I thankfully found snow.<\/strong><\/p>\n

    \n<\/p>\n
    <\/div>\n<\/div>\n

    A rugged creek crossing delivered me on snow right at the old washed-out bridge.<\/strong><\/p>\n

    Shoes off, boots on.<\/strong><\/p>\n

    The skinning was superb on grippy refrozen corn snow.<\/strong><\/p>\n

    I moved well along the creek, taking my skis off here and there for quick portages across short snowless sections.<\/strong><\/p>\n

    Mildred Meadow. Image: SnowBrains<\/figcaption><\/figure>\n

    The deep canyon felt ominous, foreboding, unpretty.<\/strong><\/p>\n

    After 6 or 7 portages, I hit Mildred Lake at 9,800\u2032.<\/strong><\/p>\n

    The Mildred Meadow is about 1 mile long and held little snow.<\/strong><\/p>\n

    Skis on the pack, long heel-strike strides until the meadow gave way to rolling snow-covered hills.<\/strong><\/p>\n

    Choose your own adventure up these puzzling humps.<\/strong><\/p>\n

    The heat slammed down on me in this moment, lending urgency to my mission.<\/strong><\/p>\n

    If everything went my way, I\u2019d be topping out around 12:30 pm, which is approximately when the chute should be fully drenched in sunlight.<\/strong><\/p>\n

    The humpy hills were the crux of the lower mountain, as they required route-finding and too many switchbacks.<\/strong><\/p>\n

    Pinner Couloir. Image: SnowBrains<\/figcaption><\/figure>\n

    I emerged from the hill country just above Lake Wit-So-Nah-Pah and had a decision to make\u2026<\/strong><\/p>\n

    Stay on the little ridge I was on and hope it connects to the plainly visible main route, or drop the 70 vertical feet down to the lake and take the straightforward path up.<\/strong><\/p>\n

    I chose the former.<\/strong><\/p>\n

    I was wrong.<\/strong><\/p>\n

    I ended up climbing an unnecessary ridge and having to rock scramble down to the far side of the lake.<\/strong><\/p>\n

    Back on track, I took a healthy break, fueled up, and got ready for the estimated 2-hour push up the final 2,000 vertical feet to the top.<\/strong><\/p>\n

    Nothing but big switchbacks and a short bootpack stood between me and the first-hand knowledge of whether or not the sneaker entrance went.<\/strong><\/p>\n

    Red Slate. Image: SnowBrains<\/figcaption><\/figure>\n

    My anxiety grew.<\/strong><\/p>\n

    Would the sneaker entrance be skiable?<\/strong><\/p>\n

    Would I have to downclimb?<\/strong><\/p>\n

    Should I have brought a rope?<\/strong><\/p>\n

    I was already spent.<\/strong><\/p>\n

    Red Slate. Image: SnowBrains<\/figcaption><\/figure>\n

    I focused on breathing, kept my head down, and started grinding.<\/strong><\/p>\n

    1,400 vertical feet and 60 minutes later, I made it to the last flat spot and took my final break of the climb.<\/strong><\/p>\n

    I checked the numbers and saw that if I moved well, I\u2019d hit the top at the 7-hour mark.<\/strong><\/p>\n

    After a few more switchbacks on skins, I donned crampons and started cranking up the booter.<\/strong><\/p>\n

    Bear tracks. Image: SnowBrains<\/figcaption><\/figure>\n

    The snow was good enough for booting and I made good time to the top.<\/strong><\/p>\n

    I crested the knife-edge ridge, gawked into the sneaker, and immediately felt relief.<\/strong><\/p>\n

    The sneaker entrance was in.<\/strong><\/p>\n

    Thank goodness\u2026<\/strong><\/p>\n

    I\u2019d been nervous about it all day.<\/strong><\/p>\n

    Sedementary. Image: SnowBrains<\/figcaption><\/figure>\n

    That\u2019s one helluva long walk only to get to the top and see that the entrance is closed and you gotta go back the way you came.<\/strong><\/p>\n

    My heart felt light, my anxiety vanished.<\/strong><\/p>\n

    I took a decent break there on the knife and drank in the classic California summit weather \u2013 no wind, warm temps, blazing sunshine, not a cloud in the sky.<\/strong><\/p>\n

    I could see Mt. Ritter and Banner, the Minarets, Crowley Lake, the White Mountains, the Sweetwater Range (where they heli-ski now), the green valleys down into the western Motherload, Yosemite, Mt. Laurel, and more.<\/strong><\/p>\n

    North Couloir of Red Slate. Image: SnowBrains<\/figcaption><\/figure>\n

    The sneaker entrance looked like a ladder as everyone before me had side-stepped down.<\/strong><\/p>\n

    I side-stepped, too, then tried a few turns.<\/strong><\/p>\n

    The snow was awful.<\/strong><\/p>\n

    Manky, sticky, sun-cooked, unconsolidated mush.<\/strong><\/p>\n

    Looking down the North Couloir of Red Slate Mountain, CA. Image: SnowBrains<\/figcaption><\/figure>\n

    I fell over a couple of times when the snow started sliding underneath me.<\/strong><\/p>\n

    I glided over to the little launch pad at the top of Red Slate\u2019s north couloir exhausted.<\/strong><\/p>\n

    I took off my skis and pack, sat down, and took another full break there, hoping my body could recover enough juice to ski with gusto.<\/strong><\/p>\n

    It worked.<\/strong><\/p>\n

    I dropped in not knowing exactly what to expect from the snow and was grateful to find 3 and a 1\/2 star corn.<\/strong><\/p>\n

    I got lucky.<\/strong><\/p>\n

    It would\u2019ve been sticky and horrible had the handful of skiers before me not skied off the rotten new snow in there.<\/strong><\/p>\n

    Thanks, guys.<\/strong><\/p>\n

    The bed surface they left corned up and skied nicely.<\/strong><\/p>\n

    The good snow gave me confidence and I skied the first pitch a bit faster than I shoulda.<\/strong><\/p>\n

    I cranked 15 fun turns before having to stop and huff the 63% effective oxygen for a minute or two.<\/strong><\/p>\n

    11 more big turns \u2013 another break.<\/strong><\/p>\n

    First glimpse of Red Slate. Image: SnowBrains<\/figcaption><\/figure>\n

    Then the finale of the run, where I was able to grunt out 39 turns down the choke, across the apron, and into the flats.<\/strong><\/p>\n

    I was smoked.<\/strong><\/p>\n

    I dropped my gear and collapsed on my pack, thrashing the air with my lungs.<\/strong><\/p>\n

    Relief, satisfaction, and pride swept over me.<\/strong><\/p>\n

    I\u2019d passed the test.<\/strong><\/p>\n

    <\/p>\n

    The skiing was sticky and weird down to Constance Lake.<\/strong><\/p>\n

    I no-skin-skinned across the suspicious blue-tinted melt-freeze lake ice to the mile-long meadow.<\/strong><\/p>\n

    I stopped at the first good-looking stream I crossed, sat down, and guzzled a liter of water directly out of the stream.<\/strong><\/p>\n

    I filled another bottle for the road.<\/strong><\/p>\n

    Skis on the pack for the walk across the meadow where I saw dozens of small trout (German browns?), brilliant green algae, plenty of dead meadow grass (still not awakened from its winter slumber), and sly coyote tracks.<\/strong><\/p>\n

    Convict Lake and the White Mountains. Image: SnowBrains<\/figcaption><\/figure>\n

    I drank in the gentle gurgling of these lazy meadow streams.<\/strong><\/p>\n

    At the edge of the meadow, I reapplied my skis and glided down to the washed-out bridge where my shoes were (with about 6 skis off walking bits).<\/strong><\/p>\n

    The dark, ominous gorge of the early morning hours transformed into a dazzling display of convoluted sedimentary rocks coming in an array of colors, favoring reds, oranges, and slate grays.<\/strong><\/p>\n

    Steep cascades bashed down the mountainsides, screaming for stillness in the lakes and meadows below.<\/strong><\/p>\n

    Miles likes it. Image: SnowBrains<\/figcaption><\/figure>\n

    I was ecstatic to get those boots off\u2026<\/strong><\/p>\n

    Shoes felt exquisite and my pack felt heavy as I guzzled my last liter of water and leaned into the trail home.<\/strong><\/p>\n

    To make it back to the car in under 12 hours, I had to cover the last 4.4 miles in about 90 minutes.<\/strong><\/p>\n

    I lingered not.<\/strong><\/p>\n

    Red Slate Mountain, CA. Image: SnowBrains<\/figcaption><\/figure>\n

    Breathing only through my nose, I long strided the miles back to the car.<\/strong><\/p>\n

    The lake felt impossibly far away.<\/strong><\/p>\n

    Once I finally hit lakeshore, I knew I could hit the car in about 20 minutes if I hustled.<\/strong><\/p>\n

    I stepped onto the parking lot asphalt 11 hours and 53 minutes after I\u2019d left it.<\/strong><\/p>\n

    I was thrashed.<\/strong><\/p>\n

    Trout in a little swimming hole. Image: SnowBrains<\/figcaption><\/figure>\n

    I struggled to exchange words with a jovial youth from Bishop named Levi, who gave me 2 fresh strawberries.<\/strong><\/p>\n

    Tart, spicy, and delicious.<\/strong><\/p>\n

    I soaked my battered feet in the lake and let the heat of the day wash over me.<\/strong><\/p>\n

    I ordered a Latin Market carne asada burrito and rolled home happy.<\/strong><\/p>\n

    I was so tired that eating the burrito proved difficult.<\/strong><\/p>\n

    Lady bugs all over up here this time of year. Image: SnowBrains<\/figcaption><\/figure>\n

    I felt like a robot seeking fuel, not pleasure.<\/strong><\/p>\n

    I don\u2019t know if I\u2019ll ever ski Red Slate again, but to me it felt like a test.<\/strong><\/p>\n

    A test of will and fortitude that my mind needed.<\/strong><\/p>\n

    I love the fact that I wasn\u2019t sure if I\u2019d make it or not.<\/strong><\/p>\n

    Making it meant a lot to me.<\/strong><\/p>\n

    Thanks, California.<\/strong><\/p>\n
