Seth Dahl

Seth Dahl, Guide

Seth Dahl grew up in Montana where he fell in love with all things rivers. Soon he taught himself how to fly fish, kayak and to row a boat. His first river job took him down the Smith River, where he pushed a gear boat and cast flies to feeding trout. He also did day trips on the mighty Missouri River and on one such trip he came across Lewis and Clark in full regalia! No joke, ask him about it.

After a time in the military, Seth decided to pack up his gear and move to Idaho, with intent to work the Middle Fork of the Salmon River, the “Emerald Queen” of multi-day river trips. Eleven years later, Seth is still deeply in love with the wilds of the river, the people that float it, and the fish that swim it.

He spends his free time on river trips taking photos and drawing. Off the water, his drive for adventure has taken him into many wild corners of this world, mostly in pursuit of whitewater and fish. Seth spends his off-season in Boise, Idaho working for his video production business called Big Cedar Media. He hopes to inspire, motivate, and encourage people through the art of visual storytelling.

Mel Pareti

Mel Pareti, Guide

Mel grew up in the rolling hills of northern New Jersey. In younger years she had a few family fun floats on the Delaware River, and in 2000 had her first taste of whitewater on the Pacuare River in Costa Rica. In 2003 after finishing up her BA in Kinesiology from the College of William and Mary in Virginia, Mel headed to Fayetteville, West Virginia to learn to guide on the New River and the Gauley River.

After that very first season spent in West Virginia, she knew that the river would always be a part of her life. With the incredible whitewater also came a family of friends and an amazing community of boaters. Mel guided in West Virginia for a few years, and then in 2006 she also began guiding rivers in Colorado.

Mel spends as much time as possible on the river and loves sharing all things great about river life. The Middle Fork of the Salmon has become a special place to Mel and she’s excited to share its beauty. When not on the Middle Fork, Mel can be found guiding trips on the Colorado River through Grand Canyon, adventuring on private river trips somewhere in the west, or at home in the mountain town of Leadville, Colorado enjoying skiing, hiking, and nearby rivers.

Will Thursby

Will Thursby, Guide

Hello all! I’m Will. I grew up in Soda Springs, Idaho, where there was not much to do other then enjoy the scenic and wonderful nature of Idaho. My lifelong high school friends and I did everything we could to be on a mountain every weekend and that still holds true for the entire bunch of us. From skiing and snowboarding, to mountain biking, rock climbing and kayaking, we continually challenged each other and created bonds that will last a lifetime.

I was introduced to the Middle Fork in 2014, and I knew this was a place I wanted to be a much as possible. I dropped my twenty plus year career as a golf professional and made my way to this wondrous Frank Church Wilderness. When I’m not on the river, you’ll find me mountain biking, struggling to get the little white ball in the hole, or in the winter, chasing the pow pow with a snowboard or skis.

I can’t wait to spend time with each of you in this most beautiful place and create memories that will last a lifetime.

Paul Paeth

Paul Paeth, Guide

Born and raised in Missoula, MT, Paul was rowing boats before he was riding bikes. Some of Paul’s earliest memories involve fishing, rafting, and camping along the rivers of western Montana with his dad. Paul started his guiding career ten years ago as a fun way to support himself while earning his B.S. degree at the University of Montana. His passion for guiding rivers has taken Paul to the remote wilderness rivers of Montana and Idaho, as well as to Chile where he guided on the mighty Futaleufú River.

Paul is now convinced that he has found the “Holy Grail” of multi-day river trips in the Middle Fork of the Salmon River and he looks forward to sharing an incredible experience with you. Paul spends the offseason snowboarding, elk hunting with his girlfriend, and waiting patiently for the next river season to begin.


Andrew ‘Drufur’ Williamson, Guide

My name is Andrew ‘Drufur’ Williamson. I was at school at The University of Alabama when a friend and I decided to be river guides for the summer in the Carolina’s. We went to work on the Chattooga River where they filmed the infamous movie Deliverance. The Chattooga hooked me immediately along with the camaraderie of the other guides.

I realized that being on a river made me feel more alive and connected to nature than anything else I had ever done. Rafting on rivers brings all walks of life together and drives everyone to leave away their worries and join others in living in the present moment. Being a river guide is my favorite thing in the world!

I’ve been fortunate enough to have guided commercially on many great rivers from Tennessee to Georgia, North & South Carolina, Colorado, Washington, and now Idaho. My first trip on the Middle Fork was in 2015 and I knew deep down I had to find a way to have this place in my life. This will be my first season with Boundary and my 11th season as a river guide. I’m am beyond stoked to be part of this team!

Chris Metz

Chris Metz, Guide

Chris began his guiding career deep in the smoky woods of West Virginia in 2000. After many full-time seasons guiding rafts down the Gauley and New Rivers and wintering in Park City to ski, he began searching for new opportunities with a shorter commute to the mountains. This led him to guide rivers in Colorado, Utah, Wyoming, California and now, finally, Idaho.

Chris is looking to use his years of experience in hospitality and on the river to create a memorable trip for his clients on the Middle Fork. When not on the river, Chris spends his time recreating in the hills and looking for adventure and wildlife with his wife and puppy dog, Herschel.



Josh Timon, Guide

Josh caught his first “bug” of running rivers with Outward Bound in 8th grade. It was that trip down the Yampa and Green rivers in NW Colorado and Utah where Josh started learning about rivers, flows, navigation and the amazing experiences of multi day river expeditions. Since then Josh has floated the Grand Canyon, Westwater Canyon, many stretches along the upper Colorado and Eagle rivers, Desolation and Grey Canyons to name a few.

What draws Josh back to the river is the adrenaline rush and respect of the power of the river as well as the experience of Mother Nature while enjoying some hard-to-reach areas only navigable by boat. The Middle Fork of the Salmon offers an environment made up of world class fishing, natural hot springs, breath taking camping sites and a camaraderie that will last for years. Josh’s passion on the river will be exhibited when you sit down for meals as he enjoys the challenge of cooking in the elements.


Brian Ladd, Guide

Brian is passionate about mountains and rivers and have spent the last 20+ years climbing, fishing, ski touring, kayaking, and rafting. He has served as an alpine patroller for National Ski Patrol and hold an active certification in Outdoor Emergency care and am a licensed Emergency Medical Technician in Oregon.

The Middle Fork holds a special place in Brian’s heart and over the years he has come to appreciate the power and sacredness of this very special canyon. His favorite memory of this river was an intimate trip with friends and brother in 2014 when he made the descent in my drift boat, which helped me refine my river reading and rowing techniques in a hard-hulled boat.

Rapids can be had anywhere. Brian feels fortunate to have the opportunity to share this special canyon and environment with new clients (new friends) and the fact that it just happens to have a dense and exciting collection of whitewater is the icing on the cake. When not on the river, Brian runs a real estate team in Bend, Oregon and spends as much time outdoors with his amazing wife and kids as possible.


Cameron Scott, Guide

Cameron Scott has called the Central and Eastern Rivers of Oregon his home waters for over 20 years. A passion for floating rivers started in his early teens and it has been his calling ever since. With an average of over 100 days a year on the sticks on the Lower Deschutes River as a Fly fishing guide for trout and steelhead and multiple trips every year on the Wild and Scenic John Day river living in a crazy hectic world centered around the solitude and beauty of river life is a life he considers well lived and it is something he longs for almost every day of his life.

His favorite river trip in the past 20 years was a cancellation permit he was able to join in on with Eric and Brian Ladd, on the Middle Fork of the Salmon last July. The river levels were at 2.4 feet and dropping and he had agreed to float the river in a brand new plastic composite drift boat that Brian Ladd had just bought. We picked it up the night before the trip in boise and spent the next 5 days trying to dodge boat crushing boulders, huge drops and skinny water slots. It was the most adrenaline filled trip he has experienced in the past 20 years and one he won’t ever forget.

When not floating rivers or chasing the elusive steelhead all over the state of Oregon, Cameron is a custom home builder in Bend Oregon.

Linda Wilton

Linda Wilton, Massage Therapist & Yoga Instructor

Linda is a massage therapist and yoga instructor who loves to live a lifestyle that blends health, wellness and the outdoors. Growing up mostly on the east coast, Linda spent a lot of time traveling around ski racing in the winter and sometimes summer ski camps. During summers she took advantage of being around the ocean and lakes of northern New Jersey and through ski camps she was introduced to bigger mountains and all the other adrenaline activities it provided.

Her passion for sliding downhill on skis led her to move to Big Sky, Montana after graduating from St. Lawrence University in 2005 with a bachelors degree in economics and environmental studies.

While living in Montana during her early 20’s, Linda spent a few years ski patrolling and summers were spent rafting the Yellowstone River. It was during these years Linda gravitated towards yoga and bodywork while seeking a physical balance to an active lifestyle. She found herself traveling to Bali for her first yoga teacher training in 2010 and a few months after was led to attending massage school in Bozeman, Montana.

Now, having 10 years of established yoga classes and a massage therapy practice in Big Sky, Linda also enjoys spending several months living in Baja, Mexico during spring and fall. She has fallen in love with surfing the warm blue waters of the Pacific Ocean and the community of Southern Baja.
