  We use a novel Monte Carlo method to study the Mott transition in an
anisotropic triangular lattice. The real space approach, retaining extended
spatial correlations, allows an accurate treatment of non trivial magnetic
fluctuations in this frustrated structure. Choosing the degree of anisotropy to
mimic the situation in the quasi-two dimensional organics,
$\kappa-$(BEDT-TTF)$_2$Cu[N(CN)$_2$]-X, we detect a wide pseudogap phase, with
anomalous spectral and transport properties, between the `ungapped' metal and
the `hard gap' Mott insulator. The magnetic fluctuations also lead to
pronounced momentum dependence of quasiparticle damping and pseudogap formation
on the Fermi surface as the Mott transition is approached. Our predictions
about the `bad metal' state have a direct bearing on the organics where they
can be tested via tunneling, angle resolved photoemission, and magnetic
structure factor measurement.
