History and Archaeology Workshops at NoLo

Dig Deeper into Colorado's Mining Legacy
History and Archaeology Workshops at the North London Mill Site near Alma

Saturday, July 25 & Sunday, August 9, 2020
Morning and Afternoon Sessions at 10:00am and 2:00pm
Free and Open to the Public


Thanks to generous funding from South Park National Heritage Area, we are again offering History and Archaeology Workshops at the NoLo Mill site. These events are free to the public, but space is limited. You must register to participate. The workshop is limited to 10 participants per session. A registration form must be completed for each participant in your group. 

These workshops will be conducted by NoLo Executive Co-Director and historian Kate McCoy and archaeologists Michelle Slaughter from Alpine Archaeological Consultants and Natasha Krasnow from Metcalf Archaeological Consultants. They are designed with the layperson in mind. Participants will learn about the history of mining in Park County and  the history of the North London Mine and Mill. They will tour the site and learn about existing features and their roles during the Mill’s operation. Participants will also learn about how archaeology contributes to what we can know about sites like the North London Mill.


The North London Mill site is located in a high alpine region about 7 miles from Colorado State Route 9 at an elevation of 11,200 ft. Be prepared for high altitude by dressing appropriately and bringing plenty of water and snacks.

Participants will need a level of fitness to be able to hike a quarter to half a mile, cross a stream on a narrow foot bridge, and maneuver around the buildings--all at high altitude.

Social distancing protocols will be observed. Masks are required when the 6 feet of social distance cannot be observed.

A four-wheel drive vehicle is needed to reach the North London Mill, though extra high clearance is not required to get to the site. The road is not technically challenging, but it is rocky and uneven in places. The road bed is wide and graded. All participants will need to take their own vehicles to the site, with only the people in their party.

COVID-19 Update

Due to the COVID-19 pandemic, we have had to cancel some of the events previously scheduled with Colorado Adventure Guides. 

Nonetheless, our funding for the next phase of the rehabilitation of the North London Office remains secure, and work is scheduled to commence sometime this summer. We are also moving ahead with plans to build an engineered creek crossing with funding from Park County Land and Water Trust. 

NoLo will comply with all state and federal guidelines in the interest of the health and safety of our contractors and volunteers. Volunteer opportunities this summer will depend upon this guidance. 

Be safe and be well.

The Birth of Colorado Backcountry Skiing

John "Father" Dyer is considered one of the 16 original founders of the State of Colorado. He was also one of the first to ski the backcountry. On 10-foot 'Norwegian snowshoes' (skis), he carried the mail over Mosquito Pass between Alma and Leadville. 

Bluebird Days!

We were pleased to host Bluebird Backcountry for 4 days of backcountry education in March at Mosquito Pass! Approximately 100 participants enjoyed great snow conditions, a tour of the North London Mill Site, and truly bluebird days. Special thanks to the Colorardo Mountain School Guides and the USFS South Park Ranger District for granting a temporary permit for the event. 

Envisioning the Rehabilitation of the NoLo Mill and Office

On February 1, 2019, we received a major grant of $154k from History Colorado State Historical Fund and $48k in matching funds from the Gates Family Foundation for work this summer to complete exterior rehabilitation of the North London Office and prepare construction documents for the North London Mill. The preservation architects of form + works design group have developed the preliminary drawings below.

The North London Mill will be adapted for re-use as a partially enclosed shelter with interpretive displays and signage on the lower level. The upper level will also feature interpretive signage and house a meeting room for educational programming, office space, and living quarters for a caretaker of the site.

The North London Office is currently being rehabilitated as a backcountry hut available for public use, similar to those of the 10th Mountain Division and Summit Huts Associations. It will sleep 10 adults and will have running water, shower, toilet, fully-equipped kitchen, and a common dining area.
