The distance dependence of interstellar extinction in the
direction of the Aquila Rift is investigated using 473 stars
observed in the Vilnius photometric system. The front edge of the
dark clouds in the area is found to be at pc and the
thickness of the cloud system is about 80 pc. The maximum
extinction AV in the clouds is close to 3.0 mag. Two stars
with larger extinction are found and discussed. Since the new
distance of the clouds is larger than the previously accepted distance,
the cloud system mass should be increased to
which is close to the virial mass estimated from the CO velocity dispersion. Additional arguments are given in favor of
the genetic relation between the Serpens and the Scorpio-Ophiuchus
dark clouds.
