An old fused graph: a 白 over a stem-like base that pictured the faint first light over a watery flat. The modern shape no longer splits cleanly, so it is treated as one glyph. Indexed under the Kangxi 白 radical, which sits at the top, though the standard form is now 皋.
No stroke data for 皐; the glyph shown is your device font, so component strokes can't be highlighted.
