Four questions for this image
Awe is the invitation. Interpretation starts by separating the subject, scale, representation, mechanism, and evidence.
1 · What am I looking at?
Yellowstone’s Grand Prismatic Spring bands intense color around a geothermal pool.
Displayed: visualization
2 · At what scale?
Landscape scale. A large scene whose pattern depends on broad viewpoint or framing.
3 · How was it represented?
Displayed media: Deterministic ICU-authored vector explanatory visualization.
Reviewed source method: Hyperspectral imaging
The source-backed claim explicitly identifies hyperspectral imaging and wavelength-sensitive comparison.
4 · What creates the visible effect?
source backed: USGS hyperspectral interpretation links variations in the microbial mat pigments to thermal gradients around the spring, creating strong color zones around the hot water.
Current visual-property tags: color, contrast.
Explanation boundary
Why it looks this way
Only source-backed claims can carry the mechanism/explanation role here. Curated or unknown material stays visibly separate.
USGS hyperspectral interpretation links variations in the microbial mat pigments to thermal gradients around the spring, creating strong color zones around the hot water.
Provenance & evidence
Know what supports the entry.
Source pages support subject identity and claims. The displayed SVG has its own representation and rights record.
It describes the relationship between a factual statement and reviewed evidence. It does not mean the SVG shown on this page is a source photograph, museum image or scientific plate.

Runtime-media boundary
Documentary source pages reviewed. Published runtime media is an original explanatory SVG visualization, not a copied source image.
- reviewed_usable · Original deterministic SVG explanatory visualizations authored for BVU004. These files are ICU-owned presentation media and are visibly labeled as visualizations, not documentary source images.

Documentary-media review
The authoritative Grand Prismatic Spring, Yellowstone page explicitly marks its source media Public Domain. BVU still does not show that documentary asset here because original bytes could not be localized and integrity-hashed in this execution environment without hotlinking.
