The Hill Country Jacal (a Mexican term referring to a lean-to structure) is a weekend retreat located on a rock ledge above Bear Creek west of San Antonio.  The simple screened cedar pole structure is oriented towards the prevailing summer breeze and creek while its stone wall shelters the living space from the northwest winter winds.  The thick limestone wall houses an outdoor shower, bunk beds and composting toilet.  The screened living space and adjacent open porch step down the hill under the simple shed roof.
