Since it was so hot in New Mexico, we figured out that in order to avoid becoming a human jerky, we'd better not go to white sand national monument during the day. So we planed to get there right before sunset, so that I can take some good pictures.
White Sand National Monument is the world's largest gypsum dune field, about 275 square miles. Because of its white color, it reflects the heat, so even we walk on it during the day, it's not that hot at all. I carried a big responsibility to go to the white sand national park. My director is a big hiking fan, his plan is to go to all the national parks. So he asked me to get him a topographic map from the park. I was looking and looking in the tourist center, but I couldn't find one. So I asked for help, and was told there is no such map, because the sand dunes move about 30 feet every year by the strong and steady wind in that area.
The weather was not very good for pictures because of the heavy haze. We took the 7 PM tour, and the guide said the haze may come from the big fire nearby. BL was following the tour, I was wandering around to take pictures. But suddenly something that the tour guide said got my attention -- how do plants survive in the moving sands?
The big problem plants have in the dune field is being buried by moving sand dunes. Plants can't walk away from a dune that is starting to bury them. Most of the time the plants simply die because they can no longer get the oxygen they need once the sand has covered them. The tour guide pointed us to some small lovely pink flowers and told us that they're going to die soon. :( To Live on top of the dunes requires very special adaptations. Only a few plants are able to live very well on the sand dunes by growing faster than the dune can move, or/and holding on to the sand by building hard pedestals.
Soaptree Yucca
Yucca is one of the plants who grow faster than the sand dune moves. When it begins to get buried, the stem of the yucca starts to grow very rapidly and pushes the green leafy part above the surface of the sand. The stem can grow as much as 12" a year, and may get to be 30' tall. When you see a yucca plant on top of a sand dune, you can be sure that beneath it is a long stem that stretches all the way down through the sand.
I really admire Yucca's vitality. It must go through hundreds of generation's death and find a way of living, what a strong desire to survive! It never gives up the passion of living! Even a plant can do this, why human being always give up their passion for life and love so easily. When some people get hurt in love, they become so afraid of being hurt again, so they loose their passion for finding real love. They just lock their heart in a safety case, and throw the key in the ocean. Then they just wander around the world with an empty body and a big cold safety case. They can never open the safety case and show their heart to other people any more. I don't want to be one of those. I want to be a yucca, always holding the passion for life, even though I failed again, I will eventually find a way to grow out. Eventually I will have the most beautiful flowers over the white sand dune.
