One of the great events in Joshua’s conquest of the Land was the miracle on the Jordan River crossing, when the Jordan River dried up ten kilometers north of Jericho, and the Children of Israel crossed on dry land.
Our Rabbis established that one who sees the Jordan River Crossing should recite the blessing "Who has performed miracles for our Fathers in this place." Today, this crossing is called the "Hogla" Crossing near Jericho. From here they traveled to Jericho via Gilgal.
According to the Biblical account, twelve stones were taken from the East Bank of the Crossing adjacent to the water to Gilgal. These stones are there to this day to remind us of the miracle.
