by Tim Smart (303-439-9627). Meet at 0800. Exit I-70 at Morrison.
Go south to first parking lot on left after freeway entrance. Scope
would be helpful! There is steep uphill walk to the ridge. Length of
trip will depend on weather and number of migrants moving. Tim has
had over 20 years of hawk watch counting in many locations across the
country – so we’ll be in good hands!!
