Few places on earth are as dark and quiet as the inside of a cave. There's a kind of impenetrable dark- ness and total silence. When we flicked off the lights, we were en- gulfed by the darkness. Not the kind you might expect on a moonless night; there were no stars, no distant lights. The darkness was absolute, total. We could not even detect our hands a few inches from our faces. There are literally hundreds of lava tubes in Central Oregon. The Deschutes National Forest has more caves on it than any national forest in the country - about 400, although most people only know about the more popular ones. The first of the day's caves for us was Lava River Cave, the longest lava tube in Oregon at almost a mile. In places the cave is 58 feet high and 50 feet Wide. Thousands of years ago, lava flowed from the flanks of New- berry Volcano, creating a channel. The sides of the channel eventually Scott Staats crusted over, forming  roof, while the fluid lava continue, t to flow. A hollow tube was left after all the lava drained out. Lava River Cave gently slopes downhill toward the Deschutes Riv- er. At 1,500 feet in, Highway 97 is about 50 feet above the roof of the cave. Much of the cave's floor is cov- ered with sand. It was once thought that an ancient river flowed through the cave, hence its name. The sand did get into the cave by water but not from a river.

Some sand could have di- rectly got into the cave through larg- er cracks and from the mouth. This process would have taken thousands of years. At the end of the cave is a sand plug. No one knows how much far- ther the cave goes past here. Two people dug out the last section back in the ,1930s but finally gave up. From the entrance to the sand plug, the cave drops gradually about 200 feet in elevation. Halfway into the cave is a sec- tion known as "Two Tube Tunnel." Here, a smaller tube within the larger tube runs about 100 feet. Volcanic stalactites known as "lavacicles" hang from the cave's ceilings and walls. Collapses in lava tubes can oc- cur from cooling and shrinkage after the lava flows out, from freezing wa- ter that dislodges rock or from earth- quakes. Without these collapses, the caves would not be discovered. From the entrance of Lava River Cave, the main tube heads northwest for about a mile. The section to the southeast continues for another 1,560 feet but is closed to the public due to loose rock. Bats use Lava River Cave and several other caves in the area for hibernating during the winter. Most are out by this time of year. Do not disturb any bats that you happen to come across. After being in the cave for an hour or two, coming back to the warm surface feels like walking from winter right into summer. Our next stop was Boyd Cave, a lava tube 1,880 feet long. As we headed down a set of metal stairs we were immediately greeted with cool air hitting our faces. When warm air hits cooler air, the end result is mois- ture. This accounts for all the inter- esting and unique vegetation at the mouth of the cave, which creates its own mini-ecosystem.

A headlamp and a small flashlight are suggested, and watch for low-hanging rocks if you don't want to come back out with a lump on your head. There are a few collapsed sections that make for more difficult walking. These Central Oregon lava tubes have quite a history. They were first used by Native Americans and later by white settlers as refrig- erators Remnants of whiskey stills have been found in some. The gov- ernment has even looked at a few of the caves for use as bomb shelters. There were a few places where all of us had to get on our bellies and crawl through smaller passageways. Anyone suffering from claustropho- bia may want to remain in the larger portions of the caves. Through these small openings, we could feel the air blowing by us. As the barometric pressure changes outside, the air will move in and out of the lava tubes. It's almost like the caves are alive and breathing. There's a spider-like creature that calls the cave home. It's called a harvestman and is very similar to a daddy long-legs. The harvestman is not a tree spider; it has 10 legs, with the front two used to capture its prey. We did spot one toward the end of the cave. We also saw some rootlets hanging down from the roof of the lava tube, which were most likely from large ponderosa pines. The cave floor at the entrance is about 30 feet below the surface while the end of the cave is about 60 feet below the surface. To reach Lava River Cave, go 12 miles south of Bend on Highway 97. The turnoff to the cave is about two miles past Lava Lands Visitor Center. To get to B0yd Cave, take Knott Road at the south end of Bend and go east 1.3 miles, then take a fight on China Hat Road. This road turns into Forest Road. 18. Go 8.1 miles and take a left on Forest Road 1819- 242. Boyd Cave is only a few hun- dred yards down the road. The road passes through the Skeleton Fire, which burned 17,000 acres in August of 1996.
