Missions
8 missions at Grand Prismatic Discovery
Mission 1
Find Grand Prismatic
Use a boardwalk or viewing area where the spring fills the frame. Try to include the bright colors or the shape of the pool clearly.
Mission 2
Find the Color Bands
Take a photo where the colors are the main subject, not just steam. Focus on the rim or surface where the colors stand out best.
Mission 3
Follow the Basin Boardwalk
Capture a section where the boardwalk clearly passes near steam or hot ground. Show how visitors are guided through the area.
Mission 4
Catch the Steam
Look for a spot where the steam is easy to see against the background. Try to show both the steam and the feature it comes from.
Mission 5
Find the Overlook Trail Sign
Look for an official park sign, trail marker, or route sign that clearly connects to this area. Make the wording or symbol readable if possible.
Mission 6
Find a Second Thermal Feature
Look beyond Grand Prismatic for another distinct thermal feature nearby. Try to show what makes it different from the main spring.
Mission 7
Look for Mineral Rims
Look for a bright or pale edge where minerals have built up around the water. Keep the mineral buildup as the main subject.
Mission 8
Big Basin View
Use a viewpoint where the basin feels large and connected. Show enough of the area that someone could tell this is a whole geothermal landscape, not just one pool.
