What effect does a large, dark boulder placed in a sunny spot have in relation to thermal regulation?

Answer

It absorbs significant heat during the day and radiates it slowly at night.

Dark materials like concrete or large boulders absorb substantial heat. When this heated mass is near a cool hiding spot, it provides a mechanism for rapid warming or cooling as the snake moves between the two.
