An umbrella-shaped shelter includes a single vertical support member either permanently mounted to a support surface, such as the ground, or removably attached to a mounting base disposed on or in the support surface. The lower end of the vertical support member may be mounted in a concrete base, removably inserted in a tubular sleeve disposed in the support surface, or may be attached to the support surface using anchor bolts, or ground anchors. In one embodiment, the lower end of the vertical support member is attached to a base including outwardly extending, radially disposed base members which, in turn, are mounted to the support surface such as by ground anchors. Concentrically disposed about and attached to an upper end of the vertical support member by radially extending frame members is a circular ring. A fabric cover is disposed over a cap on the upper end of the vertical support member and about the circular ring. Disposed on the peripheral edge of the generally circular fabric cover is a hem which is adapted to receive a cable, or rope, extending about the periphery of the fabric cover. The cable or rope is pulled tight and secured with the fabric cover disposed over the upper end of the vertical support member and its peripheral edge disposed about the circular ring to securely attach the fabric cover under tension to the vertical support member and circular ring, with tension on the cover adjustable as desired.
