Pompeys Pillar.

Pompey's Pillar

Between dawn and dusk, one can park before the gate and walk to the pillar if the gate is closed. Marmots are active in the off-hours, waddling on the lawn near the interpretive center, and even climbing on the rocks.

The rangers are very friendly and even walked us around to the front of the pillar to view some of the "graffiti" and carvings on the highway-facing side. Also spotted a huge owl hiding out in a cave.

Fantastic stop, especially if you're a fan of the Lewis and Clark expedition! A quaint, lovely, beautiful, well-cared for monument that costs only $7 per car. Don't miss it.
