I grew up in rural central Wisconsin. I’ve spent most of my adult life traveling seasonally to guide.
How many seasons have you been guiding?

When not on the Middle Fork you can find me exploring the beaches, forests, and mountains of the west coast, traveling somewhere tropical looking for surf, or hunkered down playing music and sharing laughs with friends.

Sydney Newell
Where do you call home?
I grew up in Smithfield, Utah.
How many seasons have you been guiding?
My first river trip was an overnighter on the Snake River when two years old. Most of my river experience has been on the Salmon River. However, I also grew up running various sections of the Colorado, Green, Yampa, San Juan, and Snake Rivers with family and friends. I started training on the Middle Fork when I was fifteen and began guiding on the Middle Fork when I was seventeen. I spent the last two summers as a lead guide on the Main Salmon. This is my fourth season guiding and I am excited to be back on the Middle Fork!

My favorite river meal is Salmon with fettuccine alfredo!
Three things you recommend bringing on the river?
Chapstick, lotion, and sunglasses are essential to have on the river. You should have at least two chapsticks in case you lose one to the river. It’s always good to rehydrate with lotion before crawling into your sleeping bag and the reflection of the morning sun can be blinding without sunglasses.

Favorite River Meal?
Coffee and fried rice.
Three things you recommend bringing on the river?
I’d never risk a river trip without top to bottom sun clothes (as opposed to sunscreen which can get washed into the river pretty quick) EXTRA sunglasses, and a full set of super dry thermals for sleeping or just backups!

How many seasons have you been guiding?
I’ve been guiding for 18 summers mostly in Coloma CA and a few years in Maine.

Positivity, sun protection, and your tooth brush. Everything else is a luxury.
Miles Hoover

Favorite River Meal?
Steak and beef tenderloin, on multiple occasions during my first couple years I would eat so much I’d get the meat sweats when we cooked this.
Three things you recommend bringing on the river?
It’s imperative to bring a good music taste when coming aboard my boat. I won’t leave for a trip without my chapstick and water bottle.

I love a good taco bar on Margarita night! So many choices to build your own masterpiece. And if it’s not quite right the first time around you can always make another
Three things you recommend bringing on the river?
Your favorite cotton hoodie to put on when you get to camp! Nothing feels better after a day on the river as the sun ducks behind the mountains. Running shoes are a close second. There are so many opportunities to walk or jog around camps. The third item which I really should have listed as the first most important item is a good quality rain coat or dry top that is within 30 seconds reach for that crazy 5 minute thunderstorm or the big wave rapids.

Guiding has led me to chase rivers and share experiences across South America, Central America, Africa, and throughout North America, shaping not only my career but the way I connect with people and wild places.
When not on the river…
When not on the Middle Fork, you can find me in southern Mexico spending time with my family, surfing and spearfishing, and exploring coastlines and rivers—wherever the next adventure leads.

Something fun about me…
For many years my dream was to live in New Zealand. Covid put that dream on hold but in 2022 I was able to move to NZ for a year on the working holiday visa. I bought a L300 van and lived out of it for the year. I loved my community in Milford sound were I worked as a chef and in Wanaka were I worked as a ski instructor.

Morgan Throckmorton
I grew up outside Sacramento, CA where I spent most of my time climbing, backpacking, and exploring the Sierra Nevadas. I’ve always been drawn to big, overnight backcountry adventures, and when I moved to Missoula, MT, packrafting opened up a whole new way to move through wild places. I fell in love with rivers and the sense of freedom they bring, eventually finding my way into kayaking and rafting.
These days, when not off adventuring in our van, Maybe, I spend most of my time in Salmon, ID. When I’m not at the boathouse, you can find me on the river, in the mountains trail running and mountain biking, or at home gardening in the greenhouse alongside our flock of 20+ chickens. In the winter, I am a full-time powder hound and spend nearly every day on skis either patrolling at Lost Trail or touring around in the backcountry. I’m also a proud co-handler to our certified avalanche rescue dog, Skadi, who, in her off-season, is a phenomenal boat dog that also loves the Middle Fork and looks forward to greeting everyone at the boathouse this summer!

Something fun about you…
I have a passion for nuclear energy! My senior year of college at Montana State I received a research grant to study the feasibility of implementing nuclear energy in Montana. All those hours of study showed me how I can change the world for the better and how to keep our planet healthy and thriving. It is my lifelong goal to bring nuclear energy to Montana and across the western U.S.

Brian Ladd
Brian is passionate about mountains and rivers and has spent the last 20+ years climbing, fishing, ski touring, kayaking, and rafting.
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.
Ennion Williams
Ennion has lived in Big Sky for 27 years. He spent many years working at Lone Mountain Ranch where he worked as a chef, fishing guide, manager and ultimately General Manager. He then went on to be General Manager at Big Sky Vacation Rentals, a local vacation rental company in Big Sky, for the past 5 years. Ennion has a passion for the outdoors and floating rivers around Southwest Montana.
As a fly fishing guide for the past 20 years, Ennion has a deep sense for the river and hunting down trout. Ennion first descended the Middle Fork in August of 2019 and immediately fell in love with the river and the mystique of the canyon. Ennion looks forward to guiding anglers on the Middle Fork and sharing this special place with clients.
Linda Wilton
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 bachelor’s 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.
Josh Timon
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, breathtaking 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.
Dr. Kallie Harrison
DACM, LAc, RN, LMT, Psychedelic Assisted Therapist
Dr. Kallie Harrison brings over two decades of experience in integrative medicine, blending Eastern and Western healing modalities with trauma-informed care. She began her professional journey in 2005 as a massage therapist in San Diego, eventually becoming a registered nurse specializing in women’s health, high-risk labor and delivery, and postpartum care.
Her passion for deep, whole-person healing led her to pursue a Master’s and Doctorate in Acupuncture and Chinese Medicine. After graduating, she volunteered with the Acupuncture Relief Project in rural Nepal, where she treated over 1,000 patients with a wide range of conditions. She has since continued her studies in psychedelic-assisted therapy, earning certifications through CIIS and MAPS, and deepening her understanding of how trauma, chronic illness, and emotional suppression affect the body-mind-spirit connection.
Kallie now runs a private practice in Park City, Utah, where she specializes in chronic and acute pain, women’s health, trauma recovery, cancer support, emotional regulation, and nervous system healing. She combines acupuncture, cupping, bodywork, and somatic practices to meet each patient exactly where they are. Her work is rooted in the belief that healing happens when we feel safe enough to be fully seen.
On river expeditions, Kallie offers a unique fusion of acupuncture, cupping, somatic support, nervous system regulation, and integration practices to help participants reconnect with their bodies, process emotion, and find grounded presence in wild spaces. Her calm, heart-centered approach creates a healing atmosphere where transformation feels both possible and supported.
Pat Anderson
I was born and raised on a farm in North Dakota. Later I extended my farm life to Minnesota with my husband and family. The outdoors have always been a place where I find serenity, inner confidence and a work ethic for life. I didn’t have much experience on water until I got a kayak in 2004 and was hooked! I enjoy helping our guests get registered and organized for one of the most exciting adventures of their lives with Boundary Expeditions!!
