Situated on 39 acres (16 ha) in the far northwest corner of the city, Riverside Park features facilities for every outdoor activity imaginable: baseball diamonds, football and soccer fields, basketball and tennis courts, a swimming pool, a playground, and the Ruben "Bud" Bakewell Ice Rink. Riverside Park was the last addition to Buffalo's Olmsted park system — it was not conceived and built until after Frederick Law Olmsted's death, commissioned by the city in 1898 and designed by his two sons. Riverside Park was intended to finally fulfill the elder Olmsted's dream of a true waterfront park for the city and included all the classic Olmsted elements — a meadow, footpaths, wooded thickets, and a carriage concourse — as well as pleasant minnow pools along its northern boundary. It was to have been connected to the rest of the park system by Roesch Avenue, a parkway leading north and west from Delaware Park which was never built. Sadly, Riverside Park is probably the least well-preserved of Buffalo's Olmsted parks today, owing to the construction of Interstate 190 along the canal bed and the removal of many of the historic Olmsted features. However, the scenic overlook still provides a stunning view over the Niagara River (with direct access to the shore provided by the Irene K. Gardner Pedestrian Bridge over the expressway), and the Buffalo Olmsted Parks Conservancy recently unveiled River Rock Gardens on the former site of the minnow pools, now reinterpreted as a large chain of stone-bedded rain gardens peppered with greenery, traversed by footpaths, and centered on an elegant stone arch bridge.
