Work to repair the two Visitors Center (Phelps House) chimneys has been completed.  Over the years, the mortar on both chimneys had become badly deteriorated.  Little or no mortar remained in some sections, allowing water to seep in through areas of mortar loss.  To repair the chimneys, the old crumbling mortar was carefully removed by hand.  New mortar matching the strength of the existing mortar was applied.  The repair will prevent further chimney deterioration.
