Without a doubt the best day of skiing I have ever had in the 40 years I've been at it. The views from the top made you feel like you were all alone on top of the world. Aconcagua on one side, the Pacific on the other. The terrain was varied and accessible. The snow was a few days old and still perfect. The 5000 acres allows for fresh tracks days after storms. Our guides opened up new sections that hadn't been skied yet, one guide brought us to a safe location while the other checked stability. We left it to sit and hit it the next run. The guides were friendly and accommodating, while still being saftey minded. It wasn't hard to tell they were loving it as much as we were. Every pre-run safety talk ended in a reminder to "have fun"; & not because we needed reminding. The backcountry is magical no matter where you are, being able to get a ride makes it that much more fun. I'll go back to earn some turns, now that I know where to go. $15 is nothing to pay to make sure those guys keep it going. The price for the cat runs is about a 1/4 of what you'd pay anywhere else. The best bargain in all of skiing. To sum it up, get your ass down here, you will not be disappointed.
