Help cant remember where this door is

[Underhook]

I came across a door that requires multiple key cards. I have now collected a bunch of cards and am ready to open that door. If I could only remember where it is. Its driving me crazy. Could one of you be kind enough to tell me where its at.

If you mean the door on Prime that requires Explosives in order to clear out a cave to find it, it's at the far north of the map, behind a waterfall.

Waterfall is at approximately 2498:88:1139. Cavern to door is behind and to the immediate left. Cavern on the right, filled with minerals, leads to the other waterfall.

Quite a Story about it
https://planet-crafter.fandom.com/wiki/Ikhlas
Ikhlas is a missing person on the planet. They are the sole survivor of a battleship which crashed into the Dune Desert, where it now sits as a wreck. Ikhlas' whereabouts are currently unknown, and it is not confirmed whether they are dead or alive.
The entrance to the seventh base can be found in a cave in the north of the Grasslands at 2518:90:1132. It's hidden behind a waterfall and some rocks, which need to be cleared using Explosive. To enter the base the player needs five Access Card Access Cards.
The base itself holds a lot of loot and over the course of several buildings messages on screens indicate the final fate of Ikhlas - they had built an Extraction Platform in 3044 (close by to the north).

Thanks. As it turns out I was right next to it but I was going into the cave entrance just to the right. Silly me.
