Meet Doom & Lizzy

Lizzy and Doom, owners of Four Corners Guides

With 50+ years collective experience in backcountry adventures and almost as much working in the outdoor industry, Steve “Doom” Fassbinder and Lizzy Scully know what it takes to live and play in the world’s wildest areas. Out of a desire to share our passion with others, we created Four Corners Guides.

We met  in 2015 through outdoor industry connections. In 2016, we climbed “The Cruise” in the Black Canyon on our first date and the “Naked Edge” in Eldorado Canyon shortly thereafter. And after soloing to the summit of the First Flatiron we decided we were a match made on sandstone. Shortly after Lizzy moved to Mancos, we bought an idyllic, remote cabin and 35 acres at the tip of Weber Mountain. And since 2020 we got married, wrote The Bikeraft Guide, and built our remote “basecamp,” Scullbinder Ranch.

The Guide service & the four corners guides team

Obsessed with adventuring, it only made sense for us to pursue a dream we both shared of running a base camp and adventure guide service, with Steve the head “Bikeraft Guide” and Lizzy running the business. We seek to offer adventure opportunities that, “get you on the edge of your own reality to feel things you’ve never experienced,” as Doom says. And we work hard to enhance your existing backcountry skills so you can do bigger and more exciting bike and packraft adventures, while at the same time pushing you a bit further so you can find out what you’re really made of.

To achieve those goals, we’ve trained our guides extensively. All are certified in Swiftwater Rescue Training and as Wilderness First Responders, which includes First Aid and CPR. And our two head guides, Thad & Steve, have further advanced Swiftwater Safety training, and are both Level 3 American Canoe Association (ACA) Packraft Instructors. Additionally, each year we do risk management training with Wilderness Medical Associates International and advanced paddle training with Kent Ford.

Collectively, our guides have decades of outdoor adventure experience and a plethora of skills to share with our guests. So much so, that we feel absolutely certain you’ll walk away from our courses with a deeper sense of enjoyment for both living in and utilizing human-powered tools to pass through remote landscapes. We want your experience to be the milestone in your life that you measure everything else up to
