Those diagonal lines in the sandstone are not random.
They are called cross-beds.
Cross-bedding forms as sand moves across the downwind sides of migrating dunes. When those dunes are eventually preserved as rock, their internal layers remain like a geological record of the ancient landscape.
Geologists can even study cross-bed orientation to reconstruct ancient wind directions.
Look for the layers on your next canyon experience.
