Continued popular support, led to the opening of several municipal beaches in the second decade of the 20th century. Modern beaches are formed from a combination of sand deposited by lake current, and human deposited inland sand from nearby sand-pits left by the last ice age, as well as sand dredged from the lake bottom. In 2013, Cisco, Everywhere Wireless and the Chicago Park District began Free Wi-Fi service at North Avenue Beach, Rainbow Beach, Montrose Beach, Foster Beach, and Kathy Osterman (formerly known as Hollywood Beach). The far north Rogers Park neighborhood contains a series of small "street-end" beaches that unlike most Chicago beaches are often separated by private property and therefore, unconnected to each other by public parkland. This accounts for the seemingly large number of beaches in this one neighborhood. Juneway Terrace Beach is the northernmost beach in Chicago. It is located at 7800 North and Lake Michigan. It lies within Rogers Avenue Beach and Park. It is separated from Rogers Beach by a stretch of rip rap protecting three apartment buildings. Rogers Beach lies in Rogers Avenue Beach and Park at 7705 North. Barely one block long, the park also has tennis courts. However after the lake's water level rose throughout 2019 and a January 2020 storm further eroded the shoreline, the Chicago Department of Transportation announced that riprap would replace the beach to stabilize the shoreline. Howard Beach lies in Howard Street Beach and Park at 7600 North, which is just south of Howard Street. It is perhaps 213 feet (65 m) long. Also to be depreciated as a result of the 2019-2020 lake erosion. Jarvis beach located at 7400 North and Fargo beach is located at 7432 North. Offshore stretches of riprap act to reduce erosion of this beach, which is about three blocks long. In 2015, the beach was named in honor of architect Marion Mahony Griffin. The Australian Consul General, Roger Price, attended the beach's dedication for the woman who was instrumental in the design the Australian capital of Canberra. When she returned to the United States in 1939, after her husband's death, she lived near the beach. Located at 7032 North Sheridan Road and extending for eight blocks, Leone Beach is Chicago's largest. Contiguous with Leone/Loyola Beach located at 1050 West Pratt Boulevard. Formerly named Pratt Boulevard Beach, it was renamed for local neighborhood activist Tobey Prinz by the Chicago Park District in 2014. Also known as Albion Beach, contiguous with North Shore Beach, located at 6600 North, ends just north of Loyola Avenue.
