It does snow as late as June and early as Sept., bring a some winter garb and good hiking shoes. Water bottle and lip balm. Cell signal is iffy, depends on were one stands. Free WiFi. Feel free to ask if you have questions.
Signal is usually at or near the top of anyone's list that has been through there. What position are you being considered? The summer will go by rather fast...don't be to surprised (disappointed) if you don't get everything completed that you want to do in one season.
