Martin, OSMP would appreciate your concern and conservative approach. The Matron, however, is currently open for climbing. For more info and a complete list of closures in the Flatirons, see the City of Boulder's Open Space and Mountain Parks (OSMP) closure page:

www.bouldercolorado.gov/index.php?option=com_content&view=ar>>>

And then click on the individual pdf's for maps showing specific areas and formations, in this case the Shadow Canyon pdf.

Martin, the first link you cited, showing the overview map, is just that, an overview of areas subject to closure but not necessarily closed, though they don't say, 'subject to closure'. Admittedly, OSMP could be more clear on this.

The second link you provided (press release) states at the bottom: '...closures may be lifted prior to July 31 if no raptor activity is observed...'.
