In the early part the the history of the United States, there were no roads that lead from the English populated settlements in the East to the Western part of the country. When people wanted to travel west, they would need to cross fields, streams, mountains, and valleys with no path to follow.
A trail is a path that is created by travel so that others may follow.
When people speak of the Mormon trail, they are speaking of the journey and route the early saints had to take due to persecution and being driven from their homes. There were several groups that left at different times to seek safety and a place they could worship without fear. Some left late in the fall, and their trek was filled with enormous trials as they pulled their handcarts and wagons in the snow. The trail led the saints to the Salt Lake Valley.
Other settlers followed the trail and continued to California looking for gold. The Mormon settlers created outposts along the trail so that weary travelers would be able to rest, and resupply.
Like chasing wild geese, running down rabbit trails is an exercise in futility. It means wasting time and energy pursuing leads that go nowhere - or everywhere.
