Mammoth Mountain
Snowman Report
Featuring Daily Snow, Weather, Travel, FAQ, Community & Adventure
Monday, July 13th, 2026 @ 8 AM – Good morning from Mammoth, perfect Summer weather in the high country the last few days. The mountain biking and hiking are great right now. I’m hearing from people on the trail that the fishing is good, too.
Was up at Horseshoe Lake the other afternoon, and the weather was perfect with a nice light breeze on the sand keeping you cool under the warm summer sunshine. Plenty of water in the lake, with the front lagoon about half full.
Mammoth Weather Forecast: The forecasted Four Corners ridge has changed its location to over Montana and North Dakota. This pattern change will result in a short-lived monsoon flow today and on Tuesday, and then the area will go dry mid-week.
Today’s HRRR model has instability moving into the area during the later morning and early afternoon hours with showers and possible thunderstorms at that time. Today’s action looks to be a quick mover with a possibility of dry lightning strikes.
Tuesday might turn out to be a better day for rain, especially if we get some sun early in the morning. The atmosphere should be primed for T Storm action, and storms should be slower movers, resulting in some areas of isolated flash flooding.

Travel / Road Update: All Roads are open and clear. Here is the link to the current highway webcams.
Mammoth Mountain Bike Park Report: Trail conditions are a blast on everything that is currently open in the bike park. Yes, it’s getting a bit dusty with some loose conditions in some areas. I’m hoping the monsoon flow comes true and the Mountain gets some rain on Monday. Nothing like Brown Pow Days in the High Country, as we had in the lowlands this spring.
New this season is chair 4 is running Fridays – Sundays from 10 AM onward. Trails expected to be open off the top of 4 this weekend will be Brake Through, Flow, Boomerang, Seven Bridges, and Richter. Follow Me Trail and the Bullet Downhill are closed at this time.
Also, to note that the East Bowl of Mammoth Mountain has been undergoing a much-needed clean-up and thinning operation. Paper Route, Skid Marks, Maazanitia, Juniper, Lincoln Express, and Timber Ridge trails are closed until further notice. The Forest Service has a hard course in the area, and it’s boundry is well marked, so stay out.
I was able to preview what they are doing out there, but was not allowed to take photos yet. Efforts to clean the mess on the side of Juniper Trail are impressive. We will get you some photos of the area as soon as the Forest Service allows me full access for content.
Outside of the Mountain Bike Park: Mammoth Rock Trail & Mountain View are open for riding; please note NO E-BIKES of any kind allowed on USFS Trails, however, class 1 E-MTB bikes are allowed in the Mammoth Mountain Bike Park.

Much love to You All, Snowman Out

What’s Up in the Eastern Sierra
What Ups in the Eastern Sierra
A great time to visit Mammoth Lakes and the Eastern Sierra region. With Summer in full swing, I have listed below the information people ask about most.
Town Shuttle Service: The Mammoth Transit summer system operates from Mid-May through early November and offers a convenient, fun, and friendly alternative to getting around Mammoth Lakes. Passengers ride for free on all fixed routes in town.
Hot Tip: Catch the Lakes Basin Shuttle from the Village; there is also a large bike rack to take a dozen bikes all the way up to Horseshoe Lake. Once up there, you can go around the basin and then take the lakes basin paved path trail back to town.
Here is the link to the Shuttle Service Map
Mammoth Paved Trail System: These amazing paths are located all over town via the Town Loop and the Lake Basin Path. You can park at Footloose Sports of Black Tie Rentals, rent a cruiser bike, and take off on the town loop.
You can see all the trails you can ride on this map image.
Camping: All campgrounds from Mammoth Lakes down toward Bishop are now open for the Summer. Here is the link to the USFS information page on campgrounds.
Mammoth Lakes Basin: The basin is wide open, and all trails, marinas, stores, and campsites are snow-free for the start of July. Make sure to stop into Pokoknobe Lodge and say hi to the new owners.
Local’s choice for a hike is Crystal Lake. Here is the link for more info on that hike.
Reds Meadow Road and Shuttle Service: Reds Meadow Shuttle service currently runs every Thursday–Sunday. The road is still under construction, so don’t plan on driving into the canyon for day access. For the latest information on the Reds Meadow shuttle, use this link.
Minerat Vista Point above Main Lodge: You can drive up to the Vista Point just past Main Lodge for an epic view of the Sierras. This is a great place to have lunch, as there are a bunch of picnic tables and bathrooms. There is also a nice trail for a short hike.

Mountain Biking in the Eastern Sierra: I’m working on a new website that is all about mountain biking in the area. Check out our full weekly mountain bike update at this link: https://www.easternsierramountainbiking.com/
June Lake Loop: Lots to do over at the loop. The June Lake Beach is open, as are all the little shops and places in the main part of town. Fishing has been good along Rush Creek.
I plan to take a ride up to the top of June Mountain on the Levo real soon, try it out, the views are epic, and there is nobody around most of the time.
Grant Lake is open with limited water in the back cove, and just north of the back end of the loo,p you will find the Mono Lake Visitors Center. https://junelakeloop.com/
Upper Rock Creek Canyon & Rock Creek Lake: Everything is open for the Summer in the Upper Canyon, including the resort store and cafe. Grab a piece of pie at 9,000+ feet.
Bishop Creek Canyon: All roads, campgrounds, marinas, and resorts are open. The Aspens are all filled out, and it’s a great time to explore this area. It’s peak summer crowd-wise, so slow down where the roads get tight.
Scenic Drive Ideas: This is the best time of year to take a scenic drive. For a short drive, try a loop around the Mammoth Lakes Basin. Check out the vista point and the beach at Horseshoe Lakes. Stop in for a snack at the Pokenobe Lodge (New Owners).
My Favorite is the June Lake Loop with a long stop at June Lake Beach for lunch and relaxation. Bring your own food and swimsuits.
Beware of Bears: Don’t get lazy and leave food in your car, or the bears will be inspired to rip out your window for a tasty treat. It’s happened to me twice, once I left food in the car, the second time, no food,d but the window had a slight crack, and a bear pulled it out. Learn from my mistake…
Host a View or Public Roadway Webcam: I’m looking for homes or businesses that would like to host a Mammoth Snowman webcam. We are looking for killer views of the Mammoth Area and the Eastern Sierra.
The other views people would like to see are the current road conditions in Mammoth Lakes, The Slope,s and out in Old Mammoth.
If you would like to pay it forward and share a view with the community, get in touch with Steve the Snowman today. steve@mammothsnowman.com. I have webcams in stock and ready to go, and a local licensed electrician who can do the install.
