The actual application appears to be tracking paragliders. Helium just provides the internet hotspot:
> Over the course of a week, supported by Tommy and Ryan at Lonestar Tracking, Matthew at Digital Matter, Travis at Helium, and Jeremy C (@jerm on Discord), I deployed 2 off-grid Helium Hotspots high in the mountains of Utah (one at over 8,000′ and one above 11,000′) to track 30+ paragliders as they flew during the annual Red Rocks Fly In as well as raced during the inaugural X Red Rocks Hike & Fly race.
This explains why somebody would want a hotspot in such a remote, high location.
The race itself is kind of wild:

From the Rules page:
> The task is to reach the control and turn-points defined by the Race Committee every day for three days as quickly as possible traveling only by paraglider or on foot.
I imagine you'd want good tracking data to get an idea of where you're going.
