I consider all your activities with your niche sport under Hobbies. That leaves you with zero activities for nonclinical volunteering, which to me was not addressing service orientation anyway.
Ski patrol work is comparable to lifeguard work so I'm not considering it as clinical. All your clinical experience hinges on 40 hours of shadowing and 800 hours of MA (specific area TBD).
What is your purpose as a physician? I'm having trouble seeing experiences that show you are prepared to serve others on a physician role.
With no non clinical volunteering hours and a GPA of 3.4, you will be screened out at most schools. You should accumulate 150+ hours of non clinical volunteering such as food bank, homeless shelter, etc. before you submit your application.
