Here you go: you need to head to Ametrine mountain via the Celestine Cascade (that opening there). I'll put the rest in a spoiler in case you want to search for it yourself on that location

 

Ametrine Mountain B3F, start by reaching Ametrine F1 by climbing up the Waterfall in Celestine F1 (Celestine Cascade entrance) or jumping the ledge and climbing down the Waterfall in Ametrine F2 (Calcenon/Route 3 and Route 2 entrance), open the ice-Strength puzzle by pushing the boulder from one side of the Waterfall and going through the path from the other, go through the Dive spot and through the cave opening at the right (surf over it downwards), resurface to B1F and go to the left in the ice skating puzzle, go into the Dive spot and through the cave opening at the low left into B2F (the Lapras location), go through another cave opening at the bottom left to B3F and find it next to the X Door at the left

Beware though that your Abomasnow still won't be able to megaevolve because the player can't get the Mega Ring yet. It will probably be available in E17.
