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: What it and we are all about

Obsessed with adventuring, it only made sense for us to pursue a dream we both shared of running this base camp and an adventure guide service together, 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 just a bit further so you can, “find out what you’re really made of.”

While we do offer no-frills courses where you can learn just the bike and packraft skills, Scullbinder Ranch is an integral component of Four Corners Guides. It’s remote, so you must disconnect from the outside world. The property is expansive, with three canyons emanating out three directions from the property. It’s peaceful, with the Mancos River flowing through it. And it’s equipped with 2.5 miles of trails, a cabin, glamping tents and a Main House, at which guests dine on delicious, locally-sourced food while watching the sun set over the red canyon cliffs of Mesa Verde. In other words, it’s the perfect place for you to unplug, get ready to play hard and discover more about yourself, wild landscapes and the people you’re with.

All together, we feel certain you will walk away with a deeper sense of enjoyment for both living in and utilizing human-powered tools to pass through remote landscapes. We want your experience at the Ranch and on your course to be the milestone in your life that you measure everything else up to.

Thad Ferrell

Head Bike & Packrafting Guide, Fly Fishing Magician

Thad spent his childhood traveling out West to fish with his parents. They planted a seed, and whether the branches led to climbing, biking, hiking, fly fishing, or floating the rivers of the West, he knew this was where he wanted to put down roots. Always thinking about fly fishing, and after a very narrow brush with death in 2017, Thad decided to move forward with his dream of starting a guide service. Join Thad on the San Juan River!
