As with the computer center building on Parry the building could be utilized for public use if windows are cut into the walls. The building is surrounded by a high chain-link fence. There are six metal and several 90' wooden antenna on the island, There is a dock at Japtan which will require repairs prior to being suitable for regular use. A concrete boat launching ramp is located next to the dock. We departed Japtan at approximately 1400 hundred and anchored off Runit et about 1500. Runit has a land area of .120 sq. miles and is code named Yvonne. We did not tour the entire area of Runit. We were concerned primarily with the condition of the area in the immediate vicinity of Cactus and LaCross craters. There was a concrete bunker whose interior was constructed in the form of a maze near ground "0", The bunker housed measuring and recording cquipment during the blasts. There was evidence of only limited scrub vegetation in the area. The craters can be utilized for small boat harbors if a limited amount of channel blasting is undertaken. The central portion of the west side of the island looks like a ship graveyard when viewed from the ship. There are possibly 20 or mre derelict landing craft sunk and beached in the area. Bunker Cactus qe- Lending Craft TFS a aCross Crater RUNIT The survey party left Runit island at about 1640 hrs and proceeded to Mike Crater area where we anchored for the night. Mike Crater is approximately 6000' in diameter and 168' deep. , On the following morning we took two small boats and proceeded around ~ the rims of the craters. It was difficult to explain to the represen- tatives of Ujelang what had happened to 2 1/2 of their islands. The islands of Elugelab, Teiteiripucchi and Bogererik were each ground zero for surface bursts. As a result Elugelab, Teiteiripucchi and a portion ' of Bogererik are no more, Theareas of the islands had been as follows: Elugelab (code named Flora) - .01 sq. miles; Teiteiripucchi, also sometimes known as Lidibut (code named Gene) - .031 sq. miles and Bogeirik (Code named Helen) - .050 sq. miles.
