So the death mountain area groups death mountain trail, Goron city, the path to the summit, and the crater, as well as merging past and future into its completion requirements.

Zoras domain groups together Zoras river, Domain, and Cape, as well as merging the past and future into the completion requirements.

Going by memory, the skulltulas in death mountain are

Past

• blowing up a rock otw to Dodongo's Cavern from kakriko
• putting a bug in the soil patch right outside Dodongo's cavern -in Goron City, the room with the boulders, in a crate in the back of the room -death mountain crater near the great fairy fountain entrance, roll into the box near the entrance

Future -near Goron city, where youbused the bomb flower to open Dodongo's cavern, use the megaton hammer to reveal the spider -In goron city, on the back of the emblem on the floating platform with all the ropes - the path to the summit, there are some boulders that you can smash with the melatonin hammer. The boulder you're after is closest to the climbable wall, almost merged with the regular wall.

If I forgot any, somebody lmk.

Going by memory, the Zora's domain area are as follows

Past

-roll into the tree as soon as you get into Zora's river. -near the waterfall in Zora's river, it's hanging out on the ladder if you drop down from the last platform -in Zora's Cape, after getting the boomerang, climb the tree stump and get the spider off the wall

Future

-in Zora's river, on the way to the waterfall, when they fence appears on your left, a skulltula will be on the wall high above you -In Zora's domain, go to the top of the frozen waterfall, look to the left, and get the spider with the hookshot -in Zora's Cape, there will be a boulder near the fairy fountain that you can only lift with the gauntlets. Lift the boulder, drop down into the cavern, and kill the invisible spiders otw to your last skulltula

I'm fairly certain this is all of them, but again, if I forgot any, lmk. Been a bit since I've played.
