An underground power line provides electrical power with underground cables. Compared to overhead power lines, underground lines have lower risk of starting a wildfire and reduce the risk of the electrical supply being interrupted by outages during high winds, thunderstorms or heavy snow or ice storms.

The river has dug down into the Hauterivian, and the entrance fossil gallery lies within the Urgonian. The network developed along a northeast-southwest fault. [9] The fossil gallery was probably formed in the Pliocene in a subtropical climate, 3–4 million years ago. The active system was formed during the glacial episodes of Riss II and ...
