Wildflowers in Shell Ridge

April 2, 2004

In spite of the recent warm spell, this is a late year, mostly because of the cool rainy weather in February. Therefore, normal blooming is about 2 to 3 weeks overdue. Yet, there are tens of millions of flowers on these hills we will walk today. The trouble is there are only a few different kinds of flowers. Our walk took us from the Sutherland entrance (off of Walnut Blvd.) to Shell Ridge, taking the road to the right past Bramhall Pond, up the hill to Ginder Gap, up the narrow footpath to the crest of Shell Ridge, along the summit, down the switchback, near Indian Valley school, down the hill to Indian Pond and back to the entrance again. This is about a four-mile walk and will take about 90 minutes.
