I know that the Lion Head Trail is a winter variation of the Tuckerman Ravine Trail, but what I can't find is info on avalanche danger. Is there any avalanche danger for the Lion Head Trail? If there is avy danger for the Tuckerman Ravine Trail does the Lion Head Trail detour before I reach the avy danger for Tuck, would you still be in the runout for instance? Any info is great. Also, do I need snowshoes or just crampons and axe? Thinking about an attempt in mid to late January. Thanks!
First of all, welcome and hope you enjoy it here. The eastern slope of Mt. Washington has quite a few trails and deciphering this network can be tricky at first. You are correct that the Lions Head Trail is more or less a variation of the Tuckerman Ravine Trail - as in, it leaves the Tuckerman Ravine Trail, ascends to treeline via a different route and then rejoins it on the Alpine Garden, a plateau below the summit cone of Mt. Washington. That said, the Lions Head Trail itself has a variation, called the Lions Head Winter Route. To make things more confusing, this winter route actually leaves the Tuckerman Ravine Trail at a different location than the summer route. To get to the winter route, the easiest way is to turn right on the tractor road just past the second bridge over the Cutler River (about 1.8 miles from the trailhead) as if heading towards the Harvard Cabin. After a few hundred yards the Lions Head Winter Route diverges left. A first aid cache on the right side of the tractor road marks this location. This trail then climbs steeply (at times very steeply) up to the treeline where it joins the summer Lions Head Trail.
All of this happens well before you get to any of the avalanche runout zones in Tuckerman Ravine, so this will not be a concern even in the worst of avalanche conditions. In general, the Lions Head winter route was placed where it was precisely to avoid avalanche danger. That being said, in times of exceptionally heavy snowfall, there MAY be some avalanche danger on the snowfields of the Lions Head ridge just above treeline. This however is rare; in most cases your biggest concern on the Lions Head will not be avalanches but rather the ferocious winds that often batter the upper part of the Lions Head ridge (often worse than on the summit).
The Lions Head Winter Route is the "regular" route to the summit of Mt. Washington in the winter, and because of that it usually does not require snowshoes unless you happen to go there during or immediately after a significant snowfall. Crampons and an ice axe are always recommended, both for the steep section in the woods and above treeline. Luckily the steepest section is in the woods, which means there are roots and branches to grab onto for added security. If you are generally comfortable on steep snow, microspikes will probably suffice in most conditions, unless it's very icy. However if you are relatively new to this I would go with full-on crampons for good measure.
Good luck and enjoy!
