  We report on the investigation of a very high energy (VHE), Galactic
gamma-ray source recently discovered at >50GeV using the Large Area Telescope
(LAT) on board the Fermi Gamma-Ray Space Telescope. This object, 2FHL
J1703.4-4145, displays a very hard >50GeV spectrum with a photon index ~1.2 in
the 2FHL catalog and, as such, is one of the most extreme sources in the 2FHL
sub-sample of Galactic objects. A detailed analysis of the available
multi-wavelength data shows that this source is located on the western edge of
the supernova remnant (SNR) G344.7--0.1, along with extended TeV source, HESS
J1702-420. The observations and the spectral energy distribution modeling
support a scenario where this gamma-ray source is the byproduct of the
interaction between the SNR shock and the dense surrounding medium, with
escaping cosmic rays (CRs) diffusing into the dense environment and interacting
with a large local cloud, generating the observed TeV emission. If confirmed,
an interaction between the SNR CRs and a nearby cloud would make 2FHL
J1703.4-4145 another promising candidate for efficient particle acceleration of
the 2FHL Galactic sample, following the first candidate from our previous
investigation of a likely shock-cloud interaction occurring on the West edge of
the Vela SNR.
