It is officially spring today. Are you unclear about what this scientifically mean? Check out: http://news.nationalgeographic.com/news/2011/03/100321-first-day-spring-equinox-2011-vernal-science/ .

In Chicago, spring meant snow flurries this morning. Tomorrow will be 60 degrees Fahrenheit followed by five days in 30’s and 40’s. Spring in Chicago is dynamic, confusing, and ever changing. I try my best each “spring” to wait for warmer days to arrive in May. Then when warmth occurs in April, I feel blessed.

In celebration of the Vernal Equinox. I share images taken this afternoon of “vernal pools” in our patch of Cook County Forest Preserve which is an official wetland area. This designation is best evidenced in the spring. For more information on vernal pools check out: http://water.epa.gov/type/wetlands/vernal.cfm.
