Talk:Blood Kelp Zone/@comment-45936055-20200529033808

I've been exploring the north kelp zone all day and I've already found the lifepod, the cave entrance to the Lost River and there was supposed to be an Alien structure in this biome somehwere, but where?

Once in the forest-like section of the lost river here, I did see an inactive arch partially hidden behind a waterfall. Is that what I've been looking for?

I've found myself at crater edge, in mountains, and in underground islands and met both ghosts here so I'd love to stop risking death to find this thing! Help please
