What are the key statistics on Janis Elspas’s family skiing adventures?

Based on the available content, here's what I can share:

Janis Elspas and her family are quite the skiing enthusiasts. They've been enjoying ski vacations together for quite some time. Janis's triplets have been skiing since they were 3 years old and have now surpassed her in speed and agility on the slopes. They've skied at locations like Mammoth Mountain, reaching heights of over 11,000 feet. Unfortunately, on the last day of one of their ski trips, Janis had a bad fall and broke her leg on a challenging blue-black run called Roller Coaster.

Would you like to know more about their skiing experiences or perhaps about other family adventures?
