April 12th, 2026 – 8 AM – Good morning, 14-18+ inches of new snow out on Mammoth Mountain with more expected over the next 24 hours.

Currently, the skies are cloudy, with light snow showers. Up Top, the temp is chilly at 11 degrees, with a SSW wind at 32 to 43 MPH. Main Lodge has SW winds of 4 to 17 MPH and a temperature of 18 degrees.

Mammoth Weather Forecast: The NWS has a WINTER STORM WARNING IN EFFECT till 11 PM PDT SUNDAY. Today looks for snow showers, moderate to possibly heavy at times, especially during the afternoon and evening hours. With 2-4 inches of additional snowfall today, and then 4-6 inches tonight.

Temperatures at Main Lodge today in the upper 20s and lows in the teens. Winds will be out of the Southwest at 10 to 20 mph, with gusts as high as 35-55 mph. Monday temps in the lower 30s with a 60% chance of snow showers and a possible thunderstorm.

Here is the link to WeatherGuys Powder Forecast from 5 PM on Friday.

Travel Update: Chains or snow tires are required from 17 mi north of Bishop (Mono Co) to the Nevada State Line. Here is the link to the current highway webcams.

Snow Report: Winter’s back with packer powder and powder conditions today. Temps are cold, so last night’s snowfall was much lighter than the snow on Saturday morning. Should be some fun turns. Do beware, it’s low tide below Mc Coy Station.

I would go mid to fat on the skis today. Groomers are now packing down what they can before the 9 AM opening expected today.

The base at Main Lodge is 2-3 feet, with 4 feet at MC Coy Station and 6-8 feet over the upper Mountain. Canyon Lodge is now for access only, with chair 16 the only lift still open. To note, yes, Little Eagle is closed, as are 7, 8, 9, 22, and 25.

Up Top this morning, it’s all clouded over. I doubt they get it opened today. More than likely, it will be Monday before you see the Upper Mountain open again. If the clouds lift a bit, 3 and 5 will be a go later in the day.

Unbound Parks are still going strong, with full setups at South Park, Forest Trail Park, and the Main Unbound Park.

If you’re going to ski and ride this weekend, remember that during storm cycles, Mammoth does not open any lower lifts until 9 to 9:30 AM. The mid-mountain and upper-mountain lifts are closed until patrol can clear them after the storm has moved through.

What’s Up Eastern Sierra

4-11-26 – Welcome to Spring in the Eastern Sierra. The start of April has been typical with a mix of warm days and some fresh snowfall. This weekends return to winter will help with the rapdidlay dwindeling snow pack.

Kinda shocking to see Caynon Lodge down to the white ribbon for access only to 16 and the Lodge now. No idea what happens with the pond skim, might be wise to move it to Main or the Mill.

The current snow line is sitting all the way up at around 8,300 to 8,500+ feet, and higher in areas that get direct sun. With the high snowline now, there are lots of options for things to do when conditions on the hill get too slushy or blown out to ski and ride.

Here are some ideas of what to do after you get off the hill.

Mammoth Lakes Basin: The road got plowed this week and now open to bikes and road walkes, no word on when they will open to trafiic. My bet with be by the fishing open at the end of the month. If you head up into the basin stay off any part of the lakes that is still frozen, its not safe to walk on now.

Hiking Ideas: The Sherwin Lakes Trails are melting out a bit more each day and are great for a hike. Convict Lake Trail is doable, but watch for muddy sections.Lower Rock Creek Trail is all clear and ready for a hike. Watch for Mountain Bikers.

The middle section of Rock Creek Canyon, just above Tom’s place, continues to melt out all the way up to French Camp.

Mountain Biking: Every thing below 8,500 feet is melted out now, however witt the snowfall expected this weekend that won’t be the case for a few days. If your up here in the area this weekend Lower Rock Creek Canyon and the Bishop area is the place to ride.

Check out my new Mountain Bike website (work in progress) for more information on where to ride; here is the link.

Camping: All Campgrounds in the high country are still closed. Lots of dispersed camping options are available at this time. Those are something I don’t share in our public section of the website for obvious reasons.

Spring Ski and Ride Tips: To get the most out of corn snow, your bases need structure. Spring conditions will strip wax quickly, so plan to clean and wax nightly.

A lot of the frustration people feel this time of year stems from gear that’s not dialed in.

Shops like Footloose Sports and Fast Ski Sports that support this website can set your skis up properly for spring conditions, which will make a BIG difference.

Have a great, and I hope to see you here one day soon, skiing, mountain biking, or hiking.
