There are many entrances throughout the underground garden. This is 1 of the many that started going down for more than 10 feet. It was about 85 degree F outside and it was incredibly cool underground. That was why Mr Forestiere started to dig and lived down here. Summer in Fresno can be brutal with temperature up to 120 degree F (48.8 degree C). Especially without air conditioning back then in the early 1900s'.
