Proceed to the Monitor Station in Magmoor Caverns.

Monitor Station
That door I said not to go through earlier because it went back to the ship? Guess where you're heading now. Right. Careful of Missile Turrets, the best way really is to jump off the catwalk on to the island in the middle.
Proceed to the the Shore Tunnel.
Shore Tunnel
Nothing particularly interesting here, but note that part of the enclosed bridge isn't lit properly. That'll be important later.
Proceed to the Fiery Shores.
Fiery Shores
Past the flame throwers is an interesting room with a Magmoor, some Triclopses, and a Missile Expansion. On the Island with the first Triclops is a morph ball tunnel. Take the tunnel to the other side of the room.
As you come out, you'll be facing another sort of tunnel that looks remarkably like a catwalk for morph balls with a protective rail. Treat it as such. Follow the path through the unguarded catwalk to the Missile Expansion. Do try not to get yourself killed.
For best results for going along the catwalk, don't hold the Control Stick the whole time, as that you're most likely to fall down and get killed. Instead, tap or flick it lightly to move Samus around the catwalk. Doing this will make you pay attention more to the catwalk than trying to stop in time before falling.
Proceed to Transport Tunnel B in the Chozo Ruins. Path: Transport Tunnel B, Transport to Chozo Ruins West, Transport To Magmoor Caverns East, Transport Tunnel B.
Transport Tunnel B
There is a missile expansion underneath the bridge here. Proceed to the Root Cave.
Root Cave
Your job is to go up to the nearest accessible door. You can kill the little critters if you like, but do it quickly and move up.
Proceed to Tallon Canyon via the Root Tunnel.
Tallon Canyon
If you'll look down and to your left, you'll see another half-pipe structure. Surely you know what to do. Now follow the path to the only door on this map not yet entered. There will be a few sandstone walls in the way. You can bomb through them.
Proceed to the Landing Site.
Landing Site
Follow the path along the ledge to your left. Proceed to the Alcove via the Gully.
Alcove
Here are the Space Jump Boots. Are you as irritated as I am at how close to home that was? Of course, now you're going to have to go all the way back.
Before you move on, complete the trek by stepping back out to the Landing Site and saving at the Gunship.
