It was a spectacular weekend for MITOC's annual rescue course. Everyone did very well in absorbing all of the information and applying their new skills effectively.
It certainly doesn't hurt to have a degree in mechanical engineering when you are comparing the difference between a 5:1 & 6:1 haul system!

Scott used to climb regularly on his own but these days he doesn't get out as much. So he came to SMG to get back on one of his old favorites.
Recompense with the Beast Flake variation is an all time classic. Midweek climbing on Cathedral Ledge in September is as good as it gets!

Although we're thinking ahead to winter programming, we're psyched about fall rock climbing right now. Guide Ryan Driscoll was out with Muris and Alex in Franconia Notch yesterday. They climbed on The Flatiron and The Eaglet, and it looks like they had pretty spectacular conditions. Reach out if you'd like to get out rock climbing, October is one of the best months to rock climb in the White Mountains: newhampshireclimbing.com/rock-climbing/

It’s the middle of summer and you’re probably enjoying some time near a lake, the ocean, or the mountains. But it’s not too early to think about winter trips, how about an AIARE 1 course in Hokkaido, Japan?

From January 17-19, 2027, join IFMGA guide Mark Synnott for an avalanche education course in the powder skiing capital of the world. Hokkaido, the northern most of Japan’s main islands, is known for its bottomless ch*****ne power, soaring volcanoes, onsens (natural hot springs), fantastic cuisine and one-of-a-kind culture.

We have in-depth info on the SMG website or reach out to Mark Synnott directly!

To help you cope with the heat and humidity, check out these cool photos! SMG's Hanna (Operations Manager, Guide, AIARE Instructor) and Ryan (Guide, AIARE Instructor) spent late May into early June on Canada's highest peak, Mount Logan (19,551'). In their own words:

"Our trip was to Mt. Logan in Kluane National Park, Yukon Territories. We flew onto the glacier with three weeks worth of food and fuel and loaded all of our stuff onto sleds. We worked our way up to higher elevations, double carrying through the steeper sections. A window of high pressure arrived early in our trip, and we made the decision to try for the summit on our 11th day on the mountain. Mt. Logan has this really brutal summit plateau, you have to go up and down a bunch to reach the top. It ended up being a really big day and totally kicked our butts. But we reached the summit at 6pm on June 4th, and were back at the landing strip by the evening of the 5th. In total, we spent twelve days on the mountain."

Hanna and Ryan are back in NH and enjoying summer in the White Mountains. Reach out if you'd like to get out climbing with either of them!

It's getting a bit hot out there, but it wasn't too bad in the shade at Cathedral Ledge this afternoon. The bugs were manageable too! Get in touch if you'd like to climb with us this summer. We're psyched to get out with you, whether you're on your own, with a group, or with your family (half day and full day family outings available).

We were on the Franconia Ridge Loop yesterday via the following trails: Falling Waters, Franconia Ridge, Greenleaf, and Old Bridle Path. Our timing was great as we had a clear trip across the ridge and only experienced some rain on the lower section of the Old Bridle Path. Get in touch if you'd like to hike with SMG this summer. While we're often on Mount Washington, we'd be happy to get out with you on any objective in the White Mountains.
