West Shallow Line (Jump 30)
The two shallow lines start at the columns #29 (East Line) and #30 (West line). The main line has single set of jump markers for both East and West since they are essentially opposite each other. West Shallow line is yellow kermantile.
The visibility on that line varied a lot and the line was not very straight as the teams had to change directions several times to avoid dead ends and dirty water. The layers of dirty (milky water) below clear layer were really pronounced on some areas and more spread out in others.
On the last dive on that line, the team extended it to almost the full 1,000 ft and encountered the line that the initial exploration team left in place in July 2006.
