Spartan Gold: Bullfrog Sunscreen and more

pg 135

By three-thirty...despite repeated coatings of Bullfrog Suncreen

Bullfrog Sunscreen is an actual product.

From their website:
Invented specifically for surfers back in the 80's, BullFrog quickly became known as "an amphibious wonder" up and down the California coast. Finally there was a sunscreen that was as durable in the water as the surfers themselves. Today on the beaches from Malibu to Miami, BullFrog is still trusted by those who spend hours in the sea and sun. Whether you swim, surf, sail, snorkel, ski or merely splash around, surfer tested BullFrog is a reliable and trusted sunscreen.

"See the two banyan trees sitting next to each other?"
A banyan (also banian) is a fig that starts its life as an epiphyte when its seeds germinate in the cracks and crevices on a host tree (or on structures like buildings and bridges). "Banyan" often refers specifically to the Indian Banyan or Ficus benghalensis, the National tree of India, though the term has been generalized to include all figs that share a unique life cycle, and systematically to refer to the subgenus Urostigma.

The seeds of banyans are dispersed by fruit-eating birds. The seeds germinate and send down roots towards the ground, and may envelop part of the host tree or building structure with their roots, giving them the casual name of "strangler fig." The "strangling" growth habit is found in a number of tropical forest species, particularly of the genus Ficus, that compete for light. Any Ficus species showing this habit may be termed a strangler fig.

The leaves of the Banyan tree are large, leathery, glossy green and elliptical in shape. Like most fig-trees, the leaf bud is covered by two large scales. As the leaf develops the scales fall. Young leaves have an attractive reddish tinge.

Older banyan trees are characterized by their Aerial prop roots that grow into thick woody trunks which, with age, can become indistinguishable from the main trunk. Old trees can spread out laterally using these prop roots to cover a wide area. Like other Fig species (which includes the common edible fig Ficus carica), banyans have unique fruit structures and are dependent on fig wasps for reproduction.

Though it was an uncommon phenomenon, sea caves in this area did on occasion link up with both solutional and fracture-guided caves
Solutional caves are the most frequently occurring caves and such caves form in rock that is soluble, such as limestone, but can also form in other rocks, including chalk, dolomite, marble, salt, and gypsum. Rock is dissolved by natural acid in groundwater that seeps through bedding-planes, faults, joints and so on. Over geological epochs cracks expand to become caves or cave systems.

The largest and most abundant solutional caves are located in limestone. Limestone dissolves under the action of rainwater and groundwater charged with H2CO3 (carbonic acid) and naturally occurring organic acids. The dissolution process produces a distinctive landform known as karst, characterized by sinkholes, and underground drainage. Limestone caves are often adorned with calcium carbonate formations produced through slow precipitation. These include flowstones, stalactites, stalagmites, helictites, soda straws and columns. These secondary mineral deposits in caves are called speleothems.

The portions of a solutional cave that are below the water table or the local level of the groundwater will be flooded.

Fracture caves are formed when layers of more soluble minerals, such as gypsum, dissolve out from between layers of less soluble rock. These rocks fracture and collapse in blocks of stone.
