I vividly recall this enclosure when I visited Riverbanks Zoo in 2010. An absolutely ghastly exhibit, and one wonders what AZA-accreditation inspectors thought of it.
@snowleopard I'm really surprised they've never fixed this. This is really the only bad enclosure (though not all are great) in the entire zoo and they have the space to properly exhibit this species elsewhere. Pretty sure they only had one monkey, though.
