Grand Prismatic Spring, Yellowstone National Park USA
Grand Prismatic Spring is a large geothermal pool defined by concentric bands of colour formed by heat and mineral activity. The spring sits within a flat basin with steam and runoff channels surrounding it. The composition resolves through pattern, colour, and the relationship between surface and atmosphere.

Best Light
Light works best when overhead or diffuse light reduces glare because it preserves colour separation and surface detail across the spring.
Why This Light
Season
Year-Round Stable
Summer has clearer visibility with reduced steam and stronger colour definition across the spring. Winter increases steam output, partially obscuring the surface and simplifying the scene.
Crowds
Often Busy
Restrictions
Access via boardwalks only; off-trail movement is prohibited due to fragile and hazardous geothermal terrain.
