Early morning or late afternoon light can create dramatic shadows and highlight the textures of the rock formations. Midday sun can be harsh but still offers clear views.

Drone regulations can vary by region and park. It's essential to check current local drone laws and obtain any necessary permits before flying. Respecting wildlife and other visitors is paramount.

Focus on the scale of the petrified lava, the distinct banding of the geological layers, and the sweeping mountain vistas from the summit. Close-ups of interesting rock textures are also great.
