An Apple for Starlight (G1.5 TV episode, August 21^st 1992, 11 minutes)

Summary: Starlight takes on the role of teacher when Ms. Hackney is ill. In an attempt to control her peers in the class, Starlight takes them on an ill-advised field trip where they need to use what they've learned in class to escape.

So the 'star' student gets to teach the class because the teacher is ill.

Starlight is awfully tan in the mirror.

Okay, this is all known as Ponyland.

Pony Rock.

Pinto Cave! History! Finally! Interesting that they reference Pinto at all, given that none of the ponies are... ah. Maybe that's the name they are using to refer to the Pueblo-equivalent that built that watchtower several episodes ago.

That's actually a pretty big cave. It's either a limestone system, or volcanic tubes. Most likely limestone, given the size and complexity.

Settler wagons. Old ropes and tools.

That's nice, but for it to help the pulley needs to be at the top of the slope....

Oh, okay. That makes sense. The scale is weird that the pole reaches, but it makes sense. I'm going to ignore the need for axle grease for the wheel to spin, or a channel or guide to keep the rope on the wheel. Cartoon.
