We were lost and driving on a dirt road when all the sudden we came up on a triangular craft hovering ten feet off the ground silent,

We came around a corner in the road and there was an opening with a fence around it with a white water tower stood, but the first thing we seen was the triangular craft. It was hovering ten feet off the ground and had three white lights. It was about 1000 square feet in diameter, and about eight feet tall, completely silent, we both acknowledge what we see and we look at it for a bit then it shot up in the sky to the northwest at a blink of an eye still silent. We looked at each other and we knew we had just seen something special, once in a lifetime ordeal. It was black.
