yeah it is likely.

actually all three trees are so big that you can spot from afar. You would have probably spot it IF you have not check the map first, and have the false idea where it should be.

The three trees marked on the map can be found like this

1) The first way point you come to Orodas Fjorde. There are 2 waterfalls down in the bay. If you look out of the bay, there is only one small island. The tree has a tree house (hut) on top of it.

2) the next tree is on the cliff before you reach the harbour. there is a camp next to it.

3) the last tree is on the opposite bank of the red hammer tribe after the habour. It is far up at the very top. fly in and fly up, and you will see it.
