A slalom gate which has a lower support member adapted to be inserted into the snow. There is a retractable anchoring member mounted in the support member, in a manner that downward deflection of the post about a lower pivoting connecting portion pulls the anchor member upwardly to cause it to expand outwardly into the snow, thus resisting retraction of the support member from the snow. When the gate returns to its upright position, the anchoring member retracts so that the gate can more easily be removed from the snow.

A post assembly which is adapted to be inserted into a base material, such as snow, and which can pivot upon encountering an impacting force, while being retained in said base material, said post assembly comprising: a. a lower support member adapted to be inserted into said base material and withdrawn therefrom, said support member having an upper end and a lower end; b. a main post member comprising an upper main post portion and a lower connecting portion operatively connected to said base member, said post member having a lengthwise axis, said connecting portion being bendable so as to permit said main post portion to pivot laterally about the connecting portion from a normal upright position to a downward deflected position, said connecting portion being biased to urge said post member to said normal upright position; c. a retractable anchoring member mounted to said support member, said anchoring member having a retracted position which permits said post assembly to be inserted into, or withdrawn from, said base material with little force, and an extended position where said anchoring member extends into said base material to resist movement of said support member from said base material; d. actuating means operatively connected between said anchoring member and said main post member in a manner to be responsive to movement of said main post member so that lateral movement of said post member from the upright position causes said anchoring member to move to the extended position; whereby said support member in its upright position can be inserted into or removed from the base material with relative ease, and when said main post portion is deflected under impact loading, said anchoring member moves to said extended position to resist movement of said support member from the base material.
