Good morning!
I'm new to your page so forgive me if I breach any protocols. My girlfriend and I have been here on an extended stay from our home in Steamboat Springs, Colorado. We're both fairly strong four season hikers (as are our two dogs) and are particularly fond of the Fish Creek Falls trail (in case anyone is familiar with it).
We have been hiking the South Lykken Trail mostly for the quick elevation gain at the beginning and have recently heard of the Skyline Trail which seems similar to some of the trails at home in terms of elevation gain and distance. However, at this point we're not really interested in getting too technical. My main question is: At what elevation do you begin to encounter icy inclines? We brought our MSR Lightning snowshoes and Komperdell adjustable poles, so we're set for the snow and moderate ice on relatively flat terrain, not anything requiring crampons and axes. We're basically interested in getting some hard and fast elevation gain before returning home.
A few more questions: How real is the threat of rattlesnakes here? We've been hiking at night with headlamps due to some of the warnings we've read regarding the danger. How sketchy is the Skyline, prior to where it gets technical, for dogs? (Ours hike with us everywhere we've been). How prevalent are scorpions here? (Even though we keep them leashed on hikes, the dogs always manage to nose around under a rock or two), and finally: What is up with the marbles?
Sorry for taking up so much space, but this seems like a fantastic forum and a great place to get some of the information we've needed. Obviously we haven't come across any other hikers late at night on Lykken. Thank you in advance for any information you can pass on.
