About us

Alan Cammack and Elisha McArthur both grew up boating and consider rivers to be their ultimate passion, though Elisha finds her comfort in a raft and Alan finds his in a kayak. Since 2011 the pair have been paddling rivers around the world with their daughter Charlotte. As career professionals in the whitewater industry who have ultimately loved the pursuit of private boating, Alan & Elisha had a vision to make whitewater safer and more accessible for private boaters through education, skill building and resource accessibility, and so, Canyon River Instruction was born!
Book a clinic with us today to experience the passion and gain the skills that Alan, Elisha and all of CRI's instructors embody.

Elisha McArthur

Elisha McArthur has been in Love with Rivers her entire life. Having grown up in a family of private boaters, from the age of three Elisha spent her summer vacations rafting rivers like the San Juan, the Salmon and the Chama. Life circumstances changed though and when Elisha was about twelve, her family gave up boating. The young Elisha found the River's absence in her life to be a profound loss, but within a year she had found her own way back onto the River through a dear friend and a local rafting company. By the age of fifteen, Elisha knew without a doubt that she wanted to spend her life on the river and began pursuing a career as a guide. With the help of Steve Harris, owner of Far Flung Adventures in Taos NM, Elisha was able to realize that dream, and in 1999, the summer she turned 18 years old, Elisha began guiding commercial trips on the Rio Grande in NM. Elisha has since guided on rivers across the west and in Scotland. She spent five years as a head boatman, managing small rafting companies on the Arkansas River in CO, but she has always enjoyed training new guides and found the most joy in helping others to learn a love of the river, so her switch from guiding to teaching was quite a natural one and Canyon River Instruction is the culmination of both her passion and her skills. When Elisha is not on the river she is busy homeschooling her daughter Charlotte, being a 'ski race mom,' teaching violin, performing her music, repping Tuff River Stuff river gear and enjoying a fun filled busy life!



Alan Cammack

Alan Cammack grew up paddling the rivers and lakes of the Texas hill country from an early age, but didn't get into a real whitewater kayak until the age of 14. After that, he never looked back! Having found his true passion, Alan pursued kayaking full force and became a Jr. ACA kayak instructor at the age of 16. He paddled competitively in Slalom C1 through his teens, but when he moved to Colorado to attend college at Ft. Lewis in Durango, he had the Animas River in his back yard and realized that his love of paddling resided in whitewater more than gates. After college and some years of traveling he moved to Taos NM, along the Rio Grande, where he met Elisha, and eventually the two moved to Salida, CO where they now live on the banks of the Arkansas River. Even though Alan is technically a 'guide' and spends a good amount of time on a raft, he much prefers kayaking and spent most of his river career as a 'photo boater' (aka, a professional photographer taking whitewater action shots in places only accessible by boat.) Alan can often be found in his kayak, even on snowy winter days! When Alan is not in his kayak (and often when he is) you can find him with a camera in his hand, pursuing his other passion, photography. Alan passes the off season by mountain biking, skiing, paddling in the snow, and dreaming of river season.


Aaron McArthur

Aaron McArthur also began boating at a very early age. As Elisha's older brother, he too spent his early life enjoying family rafting trips. It wasn't until much later though that Aaron found his way back to the river after the family rafting trips ended. He was always willing to rally when Elisha invited him rafting, and the siblings had many fun adventures together over the years, but it wasn't until 2014 that Aaron decided to take a formal guide school, and under his sister's training, became a professional guide. In 2017 Aaron received his ACA raft instructor certification and we are proud to have him as one of our instructors. When Aaron isn't on the water he can often be found tearing up the trails and slopes on his mountain bike or skis.
