The pictures of Frontierland in Disneyland are split into eleven sections: The introduction and the streets of the town / fort, Thunder Mountain Railroad, the Shooting Gallery, Rancho del Zocalo Restaurante, the Golden Horseshoe, the sailing ship Columbia, the Mark Twain Riverboat, the Stage Door Cafe, the River Belle Restaurant, the island and the Thunder Valley Ranch.

The Mark Twain Riverboat picks up passengers at a little structure south of Thunder Mountain Railroad.

I haven't been on it. It looks great! This is the view from Golden Horseshoe.

Here's another picture of the Riverboat in dock in Frontierland.

I'm sorry I don't have more photos of the boat itself.
