Photos: Lakewood Gulch ribbon-cutting celebrates Sun Valley, Baby Matthew

In our recent epic tome about the rehabilitation of the South Platte River, we told you about improvements to Lakewood Gulch. The trickling tributary in Sun Valley was for years walled in by concrete in an attempt to corral its flow -- a dangerous situation that proved deadly in 2007 when a two-year-old was washed away in a flash flood. On Monday, city dignitaries cut a ceremonial red ribbon on Lakewood Gulch's stunning multi-million-dollar transformation.
