Indigenous rock carvings (petroglyphs) along the Río San Juan are best photographed for raking light that reveals grooves and eroded surfaces. Look for wide environmental compositions with the river valley and close textures of carved lines. Daytime clarity helps, but late afternoon shadows add depth; crowds are typically light in this archaeological site.
