To get to the Iceberg sector you have to follow the hiking trail on the right side of the Temple. Turn left when the trail splits after the end of the Temple. Cross the Valley walking parallel to the Back Wall of the Temple and soon you should see the peak of the Iceberg block. A few meters further there is the block with the hard Projects. And straight up there is the Crimp face block and the Mushroom Arete block.
