In the original photo, you can also see the Johnson Estate in the background. When Johnson Park was part of the gigantic estate, and River Street either didn't exist, or was just a one or two-lane dirt road. Not the highway it is today.
The pastoral nature of the area, whether high tide or low tide, is just amazing. Especially when compared to what it is today. When that picture was taken, all of Teaneck was rural and with very few roads. Maybe just River Road, Teaneck Road, Cedar Lane, and barely any others. And the Hackensack Ave area going north was rural. And if fact, everything surrounding the "village" of old Hackensack was rural terrain. Farms, woods, pasture land, fallow fields, marshlands and wetlands, and some large estates. That was most of Bergen County. The villages were few and far between.
