Four pre-schoolers from Centro Las Olas, a Spanish immersion school on 26th Street, climb and play on a Glen Canyon rock formation this morning under the vigilant eye of their teacher, Bethica Quinn. Altogether, 13 children wended their way along a narrow trail circling above Alms Road. Each week the children take outings to the canyon, eventually scaling the rocks below Berkeley Way where they played and joked for nearly one hour. Looking carefully, you can see, as he children did, wildflowers blooming beneath them.
