2025/2026 season Mount Vinson expedition dispatches

The team together after touching down in Union Glacier Camp!

The Antarctic season is officially underway! The first of our Madison Mountaineering Mount Vinson expeditions teams went wheels up out of Punta Arenas and have settled in on the ice. After a scenic flight, the team took their first steps onto the frozen continent, breathing in the cold air while welcoming excellent views of Union Glacier Camp and the surrounding areas. We look to move to Mount Vinson Base Camp tomorrow. Fingers crossed for clear and sunny skies! Expedition leader, Garrett Madison checks in with this dispatch from Antarctica:

Hello! This is Garrett checking in for the first Madison Mountaineering Mount Vinson (4892m/16,050ft) climb of the season.

Today is December 4th and we made it to Union Glacier Camp (700m/2,297ft) in Antarctica! We flew in from Punta Arenas (34m/112ft) on the Boeing 757, landed at Union Glacier, and settled into our camp here. We’re hoping to fly over to Mount Vinson Base Camp (2140m/7,020ft) tomorrow, so fingers crossed for good weather.

And we’re just enjoying Union Glacier Camp here! It’s bright and sunny, beautiful scenery, great food, nice people, and really magical to be here.

So all’s well in Antarctica! We’ll check in soon.
