  The origin of Galactic cosmic rays (GCRs) remains a mystery after more than
one century of their discovery. The diffusive propagation of charged particles
in the turbulent Galactic magnetic field makes us unable to trace back to their
acceleration sites. Nevertheless, nearby GCR source(s) may leave imprints on
the locally measured energy spectra and the anisotropies of the arrival
direction. In this work we propose a simple but natural description of the GCR
production and propagation, within a two-zone disk-halo diffusion scenario
together with a nearby source, to understand the up-to-date precise
measurements of the energy spectra and anisotropies of GCRs. We find that a
common energy scale of $\sim100$ TeV appears in both energy spectra of protons
and Helium nuclei measured recently by CREAM and large-scale anisotropies
detected by various experiments. These results indicate that one or more local
sources are very likely important contributors to GCRs below $100$ TeV. This
study provides a probe to identify source(s) of GCRs by means of joint efforts
of spectral and anisotropy measurements.
