 The anchorage was a trial for a ship anchored in that location, subject to extreme tides that left the ship stranded at low tide and struck by a 4 to 6 foot tidal bore when the tide came back in twice a day.The long wait was due to the limited 35 ton cargo capacity and the weakness of the 20hp engine of the tug when pitted against the strong down stream current of the Colorado, that made a round trip to and from its destination at Fort Yuma take 12 days each.The Capacity was successfully unloaded and left the river.
