Abstract
A sand dune or snow fence having slats with a substantially triangular cross-section, rather than rectangular slats. The slats are arranged to eliminate parallel surfaces there between such that air moving between the slats is not compressed or accelerated. The non-parallel surfaces provided by the triangular slats disrupt the flow of air and generate vortices. One configuration includes multiple wings radiating from a center post and anchored on each end by an end post. The asterisk-pattern of this configuration provides a robust structure sufficient to survive extreme weather. Accordingly, this design provides the additional benefit of eliminating the cost associated with replacing damaged and lost fences of the prior art.
