Cloud base sits about 114 m above the summit, so the top should stay under a ceiling rather than in it.

About Mynydd Mawr
Mynydd Mawr is a mountain in Snowdonia, North Wales, approximately 7 km (4.3 mi) west of Snowdon itself, overlooking Llyn Cwellyn and being the northern outlier of the Moel Hebog group. A popular ascent starts from Rhyd Ddu. On its western flank are the remains of ancient settlements and field systems. The profile of Mynydd Mawr from the north is often thought to resemble an elephant lying down, and consequently the mountain is often colloquially also called "Yr Eliffant", or "Elephant Mountain" by non-Welsh speakers.
