Forest Adrift
The scene
A mature forest rides alone on open water, an island with no shore: a ragged raft of spruce and broadleaf trees swaying in slow unison as a ripple of chop passes beneath them. At the waterline the island shows its underside — a dark fringe of waterlogged logs, peat and tangled roots lifting and dipping in small grey waves — while the cold lake runs wide and empty to low forested hills under an overcast late-summer sky, a tiny distant boat far frame-right for scale. Soft, flat northern daylight; palette of slate-blue water, deep spruce green, bone-grey sky and pale amber wet wood. No text, lettering or markings anywhere in the image. 16:9 landscape
