  We have measured the 2 dimensional (2D) power spectrum of the Las Campanas
Redshift Survey on scales between 30 and 200 Mpc (q_0=0.5, H_o=100h km sec^{-1}
Mpc^{-1}). Such an analysis is more sensitive to structure on scales > 50 Mpc
than a full 3 dimensional analysis given the geometry of the survey. We find a
strong peak in the power spectrum at approximately 100 Mpc relative to the
smooth continuum expected from the best fit Cold Dark Matter model (Probability
is 2.5x10^{-4} with Omega h = 0.3 assuming a Gaussian random field). This
signal is detected in two independent directions on the sky and has been
identified with numerous structures visible in the survey which appear as walls
and voids. Therefore, we conclude that there exists a significant increase in
power on this scale and that such structures are common features in the local
universe, z <= 0.2.
