  Molecular clouds at very high latitude ($b>60^{\circ}$) away from the
Galactic plane are rare and in general are expected to be non-star-forming.
However, we report the discovery of two embedded clusters (Camargo 438 and
Camargo 439) within the high-latitude molecular cloud HRK 81.4-77.8 using WISE.
Camargo 439 with Galactic coordinates $\ell=81.11^{\circ}$ and
$b=-77.84^{\circ}$ is an $\sim2$ Myr embedded cluster (EC) located at a
distance from the Sun of $d_{\odot}=5.09\pm0.47$ kpc. Adopting the distance of
the Sun to the Galactic centre $R_{\odot}=7.2$ kpc we derive for Camargo 439 a
Galactocentric distance of $R_{GC}=8.70\pm0.26$ kpc and a vertical distance
from the plane of $-4.97\pm0.46$ kpc. Camargo 438 at $\ell=79.66^{\circ}$ and
$b=-78.86^{\circ}$ presents similar values. The derived parameters for these
two ECs put HRK 81.4-77.8 in the halo at a distance from the Galactic centre of
$\sim8.7$ kpc and $\sim5.0$ kpc from the disc. Star clusters provide the only
direct means to determine the high latitude molecular cloud distances. The
present study shows that the molecular cloud HRK 81.4-77.8 is currently forming
stars, apparently an unprecedented event detected so far among high latitude
clouds. We carried out a preliminary orbit analysis. It shows that this ECs are
the most distant known embedded clusters from the plane and both cloud and
clusters are probably falling ballistically from the halo onto the Galactic
disc, or performing a flyby.
