Touring Through the Lehigh Valley Placer Toward London Mountain


Rich with Colorado's mining heritage, close to Alma, Fairplay, Breckenridge, and easily accessible to front-range populations, the site offers an alternative to typical resort development. Our plan is to build overnight accommodations with a light footprint, in harmony with the environment, the North London Mill site, and the local community. 

Our project is named for Park County Road 12, Mosquito Pass. At its summit at 13,200', it is one of the highest mountain passes in the nation. 




London Mountain is home to the historic North London Mill site, a Park County landmark. We are working in tandem with North London Mill Preservation, Inc. (NoLo), a 501(c)(3) non-profit organization, whose mission is to plan, finance, preserve, and manage the historic structures of the North London Mill site, rehabilitating them as backcountry accommodations. NoLo has applied for funding from History Colorado and the Gates Foundation, and is working to preserve, rehabilitate, and repurpose the North London Mill site.

Your contribution is tax-deductible and will help to preserve a monumental piece of Colorado history.

Bluebird Backcountry Partnership

We're stoked to announce that we've partnered with Bluebird Backcountry for a limited time in March to offer tours to the North London Mill site, with skiing on USFS land above the Mill. 

Goals for the day are to have fun, explore easy/intermediate terrain, and impart some basic backcountry knowledge, such as using equipment, reading terrain, traveling uphill, and transitioning efficiently.  

There are still a few spots available March 16 & 17 - but hurry, they're filling up fast!

2018-19 Season

It's been a great season so far, with several tours up to Mosquito Pass. Here are some pictures.

2017-18 Ski Season

It’s no secret that this has been one of the warmest winters on record in Colorado, with the lowest snowfall in 40 years. 

It’s always useful to know what the worst is like, and we’ve seen it. That said, conditions for ski touring at Mosquito Pass were quite good, and we completed tours in early February, mid-March, and early April (with the most snow all season)! Perhaps we all need to adjust our expectations for when ski season begins and ends.

Spring 2017 Update

On Friday, April 14, we held a fundraiser at the Alma Town Hall, where we raised over $1,000 for NoLo! Around 100 people attended to hear about our plans, and to check out Fritz Sperry's discussion of backcountry skiing and safety. Many thanks go out to Nancy Comer, Alma Town Administrator; to Fritz and Allison Seymour for designing the posters; to Upslope Brewing for the beer; to Wynn Miller for all his help, and to all our sponsors for supplying swag for the raffle, and to everyone who came out that night for your support.  

The skiing was great this spring - got in several tours in March and April, including 3 days with Backcountry Magazine, which included a trip up London Mountain and down the iconic 'Wave.' 

February 9, 2017 Tour

On Thursday, February 9, we took a ski-tour up to the North London Mill and to the upper terminal of the historic tramway. 

We did a thorough snowpack analysis, which, on that day, revealed an acceptable level of stability. 

Many thanks to our guide, backcountry-guru Fritz Sperry, who wrote the book on Making Turns in the Ten Mile and MosquitoRange. Check out his website

We are now actively fundraising for the restoration of the North London Office, which we hope to have functioning as a backcountry hut as early as the fall of 2018. We are applying for a $35,000 grant from History Colorado - but will require 25% matching funds ($8,750). Your contributions are tax-deductible. Please consider making a donation today, using our PayPal link above. A contribution at the Gold level ($125) will get you a Mosquito Pass hat! Of course, larger contributions are welcome - please contact us if you would like to become a Benefactor of North London Preservation Inc.
