After my last journal entry we gradually came upon a giant water fall in the deep shaft. We fell for a half hour before the shaft began to gradually slope and slowed us down. I am amazed that we survived that fall; that we were not impaled by stalagmites formed by the rushing water. We slid at quick rate out of the shaft, to fall through the air a short distance into a pool. The room was amazing; it was lit by a strange, glowing fungus growing out of the ceiling, perhaps feeding off gasses and lime deposits. Several of the men had too much weight on their packs and were pulled under the water and sent through an underground river. Over the shortwave radios a few of the men were carrying, we received faint transmissions from the lost people. Apparently, they resurfaced, once they abandoned their packs, in another room. They told us that they could see a bright light from a bend in the tunnel. We decided that we need to get out of this room and find a way to survive, possibly escape to the surface. I will update this journal when I have learned more of our situation.
