This is a bit more than just slightly inconvenient. The trail continues forward from here, with another trail up the stairs to the right.

It is that time of year. Warming weather accelerates vascular activity, which makes foliage heavier. If evapotranspiration is inhibited by humidity and a lack of wind, the foliage can get too heavy to be supported by the trees that produce it. All that increasing weight can bring down big limbs or entire trees at the most unexpected times. The process is spontaneous limb failure.

By ‘unexpected’, I mean that it happens when there is no wind. It is startling because broken limbs and fallen trees are typically associated with wind rather than a lack of it. Gentle wind actually accelerates evapotranspiration, which relives affected vegetation of some of its weight and susceptibility to spontaneous limb failure. Aridity helps too, by absorbing more moisture.

Of course, even…
