Haleakala Climb
Can anybody share experiences climbing Haleakala. What is the average grade,
how long a ride, what level of fitness, what is the weather like? Is it doable in July? Can decent bikes be rented foe the climb? Thanks. |

I saw about a dozen road cyclists riding up; some younger and some with white hair. The average grade is only 5% (10000 feet vertical over 40 miles) with no steep sections, so the climb is more about endurance than strength. Weather tends to be sunny in the morning and evening, cloudy at the top during mid-day. |

Haleakala Climb
I made the climb about 15 years ago. I did it in October, so wasn't in
peak form, but was in good shape. I lived at 5,000', so that probably made it easier. I took about 6 hours to climb of which was 5 hours of riding time. I started at sunrise to beat the heat. It averages about 4 - 5%. The toughest part for me was the last 1/2 mile from the lookout to the summit, but the rest was very gradual. I think that anybody who does a fair bit of cycling and is in reasonable shape should be able to make the climb. Make sure you bring warm clothes, as the beginning of the descent can be quite cool, until you get to lower elevations. I was quite warm on the climb, but cooled off very quickly on the descent and had to put a jacket on and wished I had full fingered gloves for the first part of the descent as I found it cold on the fingers, until about 8,000 feet. Also, bring lots of water. Colin HGL wrote: Can anybody share experiences climbing Haleakala. What is the average grade, how long a ride, what level of fitness, what is the weather like?

This made clear to me that the tides do not occur the way they teach in school or do so inadvertently. Earth's sun and moon cause the oceans to move laterally oscillating east and west. They do not perceptibly "raise and lower" the ocean. Tidal currents well up against the land impinging on north-south running shores. These tidal currents are readily apparent when swimming, as are colorful fish and sea turtles. I found the tidal aspect of the Islands an interesting sidelight to my visit. An unexpected discovery. http://www.topozone.com/map.asp?z=4&...=l&datum=nad83 Jobst Brandt |

If the tide is high on one side of such a basin, it'll be correspondingly low on the other side, and negligible in the middle. Local features can, however, affect tides to an extent. That "cup of tea" imagery always stuck with me. cheers, Tom -- -- Nothing is safe from me. Above address is just a spam midden. I'm really at: tkeats [curlicue] vcn [point] bc [point] ca |

An unexpected discovery. http://www.topozone.com/map.asp?z=4&...=l&datum=nad83 Tides do occur as they teach in school, but they are not really a back and forth sloshing as much as a cyclic sloshing. That means there are places where the tidal elevation is relatively small, called amphidromic points, and these points are kinda in the center of an ocean basin since the tide sloshes around the center. Sorta. I think they get moved around by topography of the ocean basin and the geometry of the continents as well. The cyclic, rather than straight back and forth, nature of tides is caused by the rotation of the Earth. If the Earth were stationary, then tides would slosh back and forth in what is called a seiche wave. Of course, if the Earth didn't rotate then one side would be so hot as to not have liquid water and the other side would be so cold as to have frozen water. That would suck. Here is a way cool animation of the difference between a seiche wave and the tidal oscillation: http://tinyurl.com/z4vh3 That animation is exactly what I said. The oceans slosh mainly in the east-west direction and rise because they impinge on land masses. The bay of Fundy is a great example of how this sloshing works. The sun and moon do not lift the water more at the narrow end of this inlet, the lateral motion shoves the water up there. The important point of the animation is that you can see the tidal oscillation is a level change. There's no change in sea level in Hawaii because it is an amphidromic point in the Pacific. Here is a map showing the amphidromic points of the world's oceans, and let me tell you was I relieved when I saw that Hawaii does indeed sit right next to an amphidromic point so I didn't have to erase everything I just wrote. http://tinyurl.com/gylmd There is no change in sea level because the water only moves laterally and because the world has a tilt to its axis this is not purely east-west. In any event, the water does not rise and fall because the sun and moon "lift" it. It rises and falls because it sloshes back and forth and runs up against land masses just as your URL's show. This is not what is taught in schools or what is generally believed after having "learned" that works that way. Jobst Brandt |

As I said, I was surprised to notice that there were no significant tides in Maui and it finally struck me how it works after having my doubts about what I was told in school. Jobst Brandt |
