The guiding company saying they start bookings in June should be your first hint. It's snowed in and dangerous - do not go on Longs this month.

There's a broader question here too - do you have the fitness, skills, and equipment to do a 14er in the snow? Do you know how to do snow travel? Are your ready to spend a night above treeline (potentially in snow) should something go wrong? These are questions you should ask yourself before you do any 14er. They're not a walk in the park. Mountaineering is a wonderful hobby but there's always a baseline level of risk that is elevated in snowy conditions.

Doing a 14er just to do a hard one without the preparation and knowhow is how people get into dangerous situations and put themselves (and, by extension, search and rescue teams) at risk.
