She is a Navajo who has been back from New York for only two years, returning home after her marriage broke up. She brought her two children here so they can all be close to her mother, who has cancer.
Her city-raised kids found it hard to adapt and although Barbara had problems settling in, at least she has found a job taking tourists on guided tours through the valley. On this day we are heading away from the self-drive trail and across dry riverbeds into territory which looks desolate and deserted.
Yet there, beyond the parched creek, is a homestead belonging to a local woman who is renowned as a sculptor, and over here is where they shot that sequence from Indiana Jones where our hero descends into a pit of snakes.
This is also the land where the Anasazi peoples must have walked, long before the Navajo even dreamed.
As others go off to take yet another perfect picture of the landscape with fingers of rock reaching skyward, Barbara tells me of problems on the reservation.
Alcohol, banned on the rez, is taking a huge toll on both young and old. The Indian genetic makeup is unaccustomed to alcohol, Barbara says, so they tend to become alcoholics and are killed by the drink itself or in driving accidents.
As someone who can see her people with the eyes of an outsider, she is also suspicious of the tribal councils - they seem to take in plenty of government money or income from tourism, yet somehow it doesn't trickle down to those most in need. The schools are under-resourced, the young people have little to do, the old people have given up hope.
There is an educated middle generation keen to make progress without sacrificing tradition, but the tribal hierarchy must be respected and so ... tHer voice trails off.
Barbara is facing the sun, which is setting golden-red behind a hill, her hair blowing back in the breeze. She appears to be looking at something invisible in the distance. Possibly the past, possibly the future.
