A collection of useful data for exploring Snezhnaya Part 1 to help determine if you're missing anything, as well as provide any helpful notes and information that I've come across. Will update as needed! This is just a quick resource I'm writing for now and for easy reference.
Snezhnaya Chests
Total # of Chests: 345
(max possible on in-game achievement counter)
Chest breakdown by type:
20 Luxurious, 48 Precious, 129 Exquisite, 113 Common, 35 Remarkable
Note: The exquisite chest opened during the quest with Alyosha to access his meeting point does not affect the in-game achievement counter, but it is counted on the Battle Chronicle chest counter.
Total Missable Chests: 7
(Note: "missable" means if you do not open it while within the area it is found, it is lost to you forever, you cannot go back to obtain it)
Note: These seven chests do not count on the in-game achievement counter, but are counted on your Battle Chronicle.
The chest #, type, and location are as follows:
Act I: 1 precious, 2 common (found during the first Shadow Realm portion)
Act II: 3 exquisite, 1 common (found while exploring the fatui armory)
If you opened every new chest in Snezhnaya your Battle Chronicle should be increased by:
20 lux, 49 precious, 133 exquisite, 116 common, 35 remarkable
(remember, 8 of these do not count on the achievement counter, just BC)
Puzzles
Max # of Time Trial Counter: 31
Max # of Seelie: 13
Puzzle breakdown will require time/effort to compile, my notes were inadequate.
Cryo Sigils
733 available total & 153 max left over
Max includes sigils earned from doing quests, leveling up statue, and opening all possible chests.
Max left over is what you'll have if you obtained all sigils and then spent the 580 needed to level up all the meeting points to their maximum level.
Mora Containers

Note: Missable mora container in the House of Hesperides was fixed in 7.1 and no longer is missable. Other "missable" has been determined to not be a real mora container and is no longer visible in kitchen of the House of Hesperides.
