Last summer we drove through Pioneer to visit a historic gold-mining museum.

The young pioneers organized a community garden to learn sustainable farming techniques.

The pioneer axon extends a temporary scaffold that other axons of the neuron later use to find their proper targets.

Every July, our town holds a parade and reenactments to celebrate Pioneer Day.

During Pioneer Days, the town hosts a parade, historical reenactments, and a fair celebrating its founding families.

The museum displayed several pioneer scarves donated by descendants of the settlers.

Before the parade, each child tied their pioneer scarf with trembling fingers.

The young pioneer proudly marched in the parade, holding the red flag.

After the volcanic eruption, mosses and lichens acted as pioneer species, slowly building soil and making the landscape habitable for other plants.

During development, pioneer axons establish the initial trajectories that later-growing fibers follow.
