Roundtrip Mileage - 12 miles (approx)
Crew: Joe, Prakash

NOAA conjured up a fantastic weekend forecast for the high country in general and the stage seemed well set for a 14er. After some incessant haggling I managed to convince Joe to give up delectable alpine ice routes to climb a mind-numbing heap of rubble instead. The plan included lugging skis to the top and finding something worthwhile to ski down. Neither of us had been up in the high country in over a month thanks to extended vacations at or below sea level. We were both interested in a warm-up and were both interested in a preliminary snowpack assessment. I was also excited to test my newly acquired overkill mitts (OR Alti mitts) on a winter 14er for the first time. We also carried standard avalanche gear – Beacon, probe, shovel plus first aid kits, sam splint, spare parts, stove and emergency bivy gear.

We got to the winter trailhead at 8:15AM after driving around for a little while and getting stared down fiercely by an honest gas station owner whose bathroom I shamelessly used without purchasing any of his fine goods. Trailhead directions from 14ers.com mention taking Monroe Street to Toledo St. at the South end of downtown Leadville. It’s probably worth noting that Monroe Street is now unmarked where it meets US 24. If you see a turnoff for CR-6 on your left while following 14ers.com directions, you’ve gone too far.

Snowpack Shear Tests

We skinned up and set out along the road shortly after 8:30AM. There were skin tracks heading up it so trail-breaking was a non-issue.

Skinning up the Sherman road

The first objective of the day showed up after a short while of un-interrupted skinning. A more un-picturesque heap of rubble than Sherman is yet to be seen but it was going to be a glorious day nevertheless.

Sherman makes an appearance

A short while before arriving at the summer trailhead at 12000’ (it’s 3 miles to this point) Joe decided to test the snowpack. A few jumps on a Southwesterly snow-slope below the road produced a clean shear, releasing a 6 inch to 1 foot thick slab that ran five feet.


Closer look at the fracture

We skinned on a little further up the road and Joe decided to test the slope above the road…

More snowpack testing

A few jumps on a similar aspect as before produced nothing and he skinned a few feet and began skiing down producing a large ~60 yard (maybe more) long clean fracture line varying in depth from a few inches to a foot. It ran a few feet down to the road.

Sherman Ascent

These interesting discoveries strongly suggested conservative route choices for the rest of the ascent and ski descent. We stopped to brew up some noodle soup near the upper TH at 12000’. Beacons went on and were tested after brunch. Some questionable terrain remained prior to attaining the dry upper West Slopes of Sherman. Joe led the questionable areas. As the more experienced BC traveler his decision making is far quicker than mine. I followed without debate. We stayed as high as possible on most slopes and close to rocks and tundra whenever they were available.

Safe Route Selection

One gully had slid earlier showing debris.

Wind lip and Slide Debris

More avalanche debris coming from Sheridan had slid down into the prominent gully on Sherman’s W. Slopes on a more active avalanche day.

Debris from Sheridan

We were glad to finally be gaining elevation after miles of skinning a flattish road. We were soon on the saddle between Sherman and Sheridan.

Sherman - Upper W.Slopes

After a short sugar / water break we continued on to the summit. Wind picked up and balaclavas went on. I always remember baklava when I put my balaclava on… Note to self: Bring baklava on next winter hike. After a long ridge walk we reached the summit just before the safe turnaround time. We would have no time to relax on the summit though. We decided to start heading off to Dyer after a couple summit pictures and half a power bar.

Traverse to Dyer and Descent

We began heading over to the saddle between the Geminis. We crested the cleavage between the Geminis and headed down to the ridge over to Dyer quickly. Some cornices / wind lips appear on the ridge and are easily avoided.

But the summit had to be reached first. Crunchy snow was available, beautiful, solid and perfect for climbing. These conditions produce a beautiful feeling. Joe built a staircase…

The summit was reached. It took 1:15 to traverse over from Sherman. We ate some food and drank some Gatorade that had by now turned into a delicious icy slurpy.


Thanks to the relatively quick time to traverse we didn’t need to rush the descent… which was great for me personally, since I intended to spend most of the descent skiing the available trap crust ludicrously fast, with no control, falling on my mug with obscene regularity. Joe watched patiently and shook his head in abject dismay. I cast a veil of modesty over the numerous pictures of me planting my face in ‘crap’ crust. Instead, here are a few more picturesque ones of Joe’s descent…

Skiing into the sunset

Quick time was made on the descent (compared to my past experiences with snowshoes). We were back at the car shortly after 5. A safe and fun first winter ascent for 2010 is in the books.

Thanks Chris. I'll keep you posted if we decide to go and do some other 14er this Winter.
