I am not aware of what constitutes illegal guide service. We are a group of friends that want to climb Rainier. One of our original climbers was someone who had guide experience. He since has had to change plans. We submitted for our climbing permit back in March when the applications opened and our group has changed. We were just trying to provide some incentive for someone to help us out, but hey if someone will climb with us because we have the permit and we are a good bunch of guys that is preferred but we wanted to offer a way to compensate for someone’s time. We want to climb but we all cannot afford the $1400/person the guide service charge.
From what I can find on the internet, there is a title 36, code of federal regulations that prohibits unauthorized commercial climb of Mount Rainier. This is a private group so this does not apply. If the person was part of a company and promoted their services as such I would see how this would apply but again this is a private group and we are looking for an individual(s) to assist us on their own time.
