Birches

These hill top birches were swaying in the stiff afternoon breeze and reminded me of half remembered lines from Robert Frost's 'Birches'
'When I see birches bend to left and right
Across the lines of straighter darker trees... black branches up a snow-white trunk.

The path up to the trees (See extra) was almost clear of snow. The white patch on the rock is a form of crustose lichen.
