I'm not sure if there is much of a point in writing this, but here it is nonetheless...
I was in Snowdonia this weekend and I had 2 very nice days out, one on Y Gribin (Glyders) and one on Y Garn (the normal path from Llyn Idwal). Both days were very enjoyable, and as much as I would have liked to have been climbing gullies or winter only routes, I checked the BMC Cwm Idwal winter climbing information page and saw that the turf was nowhere near frozen. The snow was very soft and no crampons were required (on the paths I was on).
In fact, even without this information page, it was still obvious that underfoot the ground was not frozen especially as you could see grass/mud poking out of the snow in gullies such as Banana Gully on Y Garn.
Despite this plethora of information and observations, I still saw people in Banana Gully and Hidden gully, hacking their way up with no regards to the vegetation beneath. The climbs can't have even been that great as it was mostly unconsolidated powder that was less than 5 days old all the way up.
Without starting a witch hunt, the pair in hidden gully are on their 'first winter climb' seem uneducated to this, so if this can highlight the importance of doing winter routes in the correct conditions then it's a good outcome, also, you might want to plan your descent and take a map/compass with you next time! I cannot say anything about the person in Banana Gully, but I presume similar.
